Legacy results page

With all critical issues now resolved, access to the legacy results page will be discontinued on 22 July. From that date, the new results page will become the default experience, and the option to switch back to the legacy results page will no longer be available.

Upcoming improvements

The following enhancements will be released in an upcoming update:

• Publication year sorting
• Extension of the publication year filter
• Highlighting issue

We appreciate your feedback and patience as we continue to enhance the new results page.

Results page – Faster and more intuitive to use

We are excited to introduce an improved Results Page, designed to make searching, filtering, and reviewing results faster, clearer, and more intuitive.

This update is part of our ongoing effort to modernize the platform and ensure a more consistent, accessible, and reliable experience across Embase.

You will notice a cleaner, more structured layout that adapts better to different screen sizes. One of the key focuses of this release was to improve accessibility. The new Results Page is designed to better support all users, including those using assistive technologies, making it easier to navigate, read, and interact with content.

What’s new?

1. Search bar simplified

   The new layout organizes key quick limit options more clearly, making it easier to refine your queries.

   

   Core options such as Mapping, Date, Fields and Quick limits are available.

   Some limits have been repositioned to improve usability -

   • EBM limits are now available within Quick limits
   • Previous limits such as Publication types, Gender, and Age have been removed from the top bar, they are now available as individual filters within the results panel, where they are easier to apply and manage.
   • We have also introduced a dedicated Language filter to make language selection more straightforward.
   • Additionally, options previously grouped under Animal limits can now be found under the Study type filter.
   • Some low usage quick limit options like ‘With molecular sequence number’, ‘With clinical trial number’, ‘MEDLINE Article in Press’, ‘MEDLINE In Process’ have been removed from the Quick limits. These capabilities are still available and can be applied by adding the following queries to your search:

     • With molecular sequence number à [msn]/lim
     • With clinical trial number à [clinical trial number]/lim
     • MEDLINE Article in Press à 'article in press'/it AND [medline]/lim
     • MEDLINE In Process à [in process]/lim AND [medline]/lim

   Overall, these changes are designed to ensure all functionality remains available in more intuitive locations.

2. Improvements to search History

   You can now expand or collapse the full history section, making it easier to focus on what is relevant. Individual queries can also be expanded or collapsed, helping you manage more complex search strategies.

   We have added support for the NOT operator, giving you more flexibility when combining queries. The editing experience has also been improved, with clearer indications when results need to be updated for a particular query.

   Additionally, features like RSS feeds and email alerts have been repositioned to make them easier to access in context.

   

3. Result panel and record view

   We have enhanced how record information is presented. Key information such as publication type and source is now easier to spot immediately. We have added a banner to easily identify the retracted articles.

   It is now easier to recognize when highlighted terms are present within the Abstract and Index terms, even when they are collapsed. An ellipsis (…) next to the section indicates that additional highlighted terms are available but currently hidden.

   Bulk and individual record selection have been combined into a single, unified interaction. Sorting options have been converted to a dropdown to make better use of space.

   

   

4. Filters

   Filters in terms of functionality remains the same but some improvements have been introduced:

   • In the old view, the Sources filter was displayed using a visual bubble chart, which was harder to interpret and interact with, when the comparing values or selecting specific sources. In the new version, sources are presented in a clean, structured list with checkboxes and visible result counts.

   This makes it much easier to quickly scan available sources, understand their relative sizes, and select one or multiple options.

   

   • Gender filter has been renamed to Sex/Gender and has been updated from visual representation to a standard list with checkbox.

   More option available - female, hermaphrodite, intersex, male, transgender

   

   • A new Language filter is now available. This option has been moved from the Quick limits section below the search bar into the filters panel for easier access and improved usability.
   • + More has been renamed to View more, the layout has been updated to display 30 items in one column, however the functionality remains the same.
   • Triple linking filters (Drugs, Disease and Device) have been redesigned. You can access this feature by clicking the arrow next to a term. It will open a view allowing you to refine your search by combining a term with relevant subheadings and linked concepts.

   This enables you to build more precise queries by:

   • Selecting a term (e.g., drug, device, or disease)
   • Add a relationship (e.g such as adverse drug reaction)
   • Further refining with specific related concepts using SELECT option

   Your selections are clearly displayed at the top, making it easy to understand how your search is constructed.

   

   This will open a view with the available subheadings for the selected drug/disease/device. To refine it further click on the SELECT option.

   

New Results page migration plan (one month transition period)

At the start of every session, by default you will land on the new Results page after running. You have the option to switch back to the legacy Results page by clicking on the option ‘Temporarily switch to the old results page’.

If you switch pages, your choice will be remembered for the duration of your current session only. You can also switch back to the new results page from the legacy results page at any time.

After the transition period, the legacy results page will be retired, and the new results page will become the default page.

More clinical trial data available on Record Details Page

We are excited to announce a major update to the Clinical Trial record details page in Embase. This redesign is based on your feedback and aims to make trial information more comprehensive, easier to scan, and faster to access.

What’s new?

1. Enhanced header section

   In addition to the official title, you can now access key information like trial status, tag indicating whether results are available, the most recent update date from clinicaltrials.gov in the header section.

   

2. Study Overview

   The abstract section has been renamed to Study Overview. It includes both a Breif Sumary and Detailed Description.

3. Added more information about the study (new sections added)

Added retraction indicators for tombstone (retracted) records

For the tombstone (retracted) records, we have added a prominent retraction banner at the top of the Record Details page and the Cite button has been disabled for these items.

This update will help you to quickly identify the retracted records, and it reduces the risk of citing retracted work. This change is only applicable to the tombstone (retracted) records.

Fixed bugs

1. Resolved issues affecting the CITE button functionality
2. Accessibility improvement in alignment with WCAG 2.1 AA standards

As part of our commitment to provide comprehensive coverage, we will be actively backfilling clinical trial data from the May update through to September. 

Embase will ingest around 65,000 clinical trial records from ClinicalTrials.gov to complete the backfill from the May release.

These additional clinical trial records will be added between 13th October to 16th October 2025. We will be adding 20,000 trials per day and the process will complete by 16th October.

During this period, you may notice an increase in the number of search results as the new content becomes available.

Embase.com

During this period, you may notice an increase in the number of search results as the new content becomes available.

To exclude clinical trials from your search results or saved searches or saved list, add any one of the following conditions to your search query:

• NOT 'clinical trial'/it (this excludes based on publication type)
• NOT 'clinical trial':dtype (this excludes based on database collection)
• NOT 'clinicaltrials.gov'/jt (this excludes based on the journal title "clinicaltrials.gov")

The clinical trials will not be included in email alerts.

API

When this data load takes place, the API queries will return clinical trials by default, in the same way they are included in the embase.com search results.
To exclude clinical trials from your API results, add any one of the following conditions to your search query:

• NOT 'clinical trial'/it (this excludes based on publication type)
• NOT 'clinical trial':dtype (this excludes based on database collection)

Several bug fixed

As part of our continuing effort to expand content sources for your research, we will soon be adding Clinical Trials to Embase!

What are clinical trials?

Clinical trials are research studies that test the safety and effectiveness of new treatments, interventions, or medical devices. These trials are conducted to gather data and evidence to determine whether a new medical approach is safe, beneficial, and superior to existing treatments. Clinical trials play a crucial role in advancing medical knowledge, improving patient care, and developing new therapies for various health conditions.

What is clinicaltrials.gov?

ClinicalTrials.gov is a comprehensive online database provided by the U.S. National Library of Medicine, which serves as a registry and results database of publicly and privately supported clinical studies conducted around the world. The database contains information on a wide range of clinical trials, including those investigating new drugs, therapies, medical devices, and treatment approaches across different medical conditions and patient populations.

Researchers, healthcare professionals, patients, and the general public can access ClinicalTrials.gov to search for ongoing and completed clinical trials, review study details, eligibility criteria, and outcomes. The database serves as a valuable resource for individuals seeking information about participating in clinical trials, staying informed about the latest research developments, and contributing to the advancement of medical science.

What will Clinical trials look like on Embase?

On the 'Results page', all Clinical trials will have a "CLINICAL TRIAL" label, so users can easily recognize this type of content.

On the 'Record Details Page', Clinical Trials records can be recognized in the additional information section, which includes:

• Publication Type: Clinical Trail
• Embase identification number (PUI): LNCT******** (this includes the original NCT number of that clinical trial)
• Source of indexing: Clinical Trials
• Source type: Clinical Trial Repository
• Abbreviated journal title: clinicaltrials.gov

How to access and how to limit clinical trials 

Clinical trials will be added to the Embase general collection and will be available to all users at no additional cost.

When you search on Embase.com, you will now see a broader range of search results. This includes clinical trials alongside other content types such as articles, preprints, and conference abstracts.

If users wish to exclude clinical trials from their searches, they have to use query syntax as explained below.

New Clinical Trials Filters Available 

Results filters below the search bar

• Sources – Limit your content selection to only clinical trials by ticking the new ‘Clinical trials’ database collection option
• Publication type – Limit your content selection to only clinical trials by ticking the new ‘Clinical trial’ option

  • Use AND 'clinicaltrials.gov'/jt to get results that ONLY contain documents under the journal title "clinicaltrials.gov".

Indexing

Clinical trials will have the latest Emtree indexing (Emtree 2024.3). This will be automatic indexing based on the title, brief summary and detailed description.

Impact on users

We are excited to announce that we will be adding approximately 20,000 clinical trials per day to Embase.com. This means around 100,000 new clinical trials will be added each week. This process will take up to 6 weeks to complete. By 16^th June 2025, all trials from clinicaltrials.gov will be on Embase.

During this time, if you do not apply filters to exclude this new content, you may notice an increase in the number of search results you receive.

Existing saved searches

Running saved searches after the release of Clinical trials will generate more results because results will include clinical trials along with the other content types (i.e. articles, preprints, conference abstracts, etc).

To exclude clinical trials from your saved searches, update to add one of the following filters to your search query:

• NOT 'clinical trial'/it  (this excludes based on publication type)
• NOT 'clinical trial':dtype  (this excludes based on database collection)
• NOT 'clinicaltrials.gov'/jt (this excludes based on the journal title "clinicaltrials.gov")

This will ensure clinical trials are not included in your search results.

New saved searches

Users will be able to create new saved searches which include or exclude clinical trials.

To exclude clinical trials from your new saved searches, add one of the following filters to your search query:

• NOT 'clinical trial'/it  (this excludes based on publication type)
• NOT 'clinical trial':dtype  (this excludes based on database collection)
• NOT 'clinicaltrials.gov'/jt (this excludes based on the journal title "clinicaltrials.gov")

To search only for clinical trials, add one of the following filters to your search query:

• AND 'clinical trial'/it
• AND 'clinical trial':dtype
• AND 'clinicaltrials.gov'/jt

Email alerts

Clinical trials will not be included in email alerts following this release. In the future, we plan to add the ability for the user to include or exclude clinical trials from their email alerts like we have done for preprints.

API

API queries will return clinical trials by default, in the same way they will be included in the embase.com search results.

To exclude clinical trials from your API results, add one of the following filters to your search query:

• NOT 'clinical trial'/it  (this excludes based on publication type)
• NOT 'clinical trial':dtype  (this excludes based on database collection)
• NOT 'clinicaltrials.gov'/jt (this excludes based on the journal title "clinicaltrials.gov")

Flat Files

Starting from 5^th May 2025, the update folders will begin to include this new content, and the subsequent backfile will then contain the full CT backfile.

We will add approximately 20.000 clinical trials per day (i.e. 100.000 per week) over the course of around 6 weeks. By 16^th June 2025, all trials from clinicaltrials.gov will be on Embase.

Important dates

Now: users can apply the new clinical trials limits and filters for their queries (e.g.  'clinical trial':dtype;  'clinical trial'/it;  'clinicaltrials.gov'/jt) to API queries

16th June 2025 - all trials from clinicaltrials.gov will be on Embase

Clinical Trials Document-Specific XML tags

We are implementing the following tags in the flat file XML output, to make it easier for users to identify this content.

These updates will appear only in the Clinical Trials XMLs located in both the daily update folder and the bulk DAAS flat file folder. Other content types XMLs (e.g. articles, preprints, etc) remain unchanged.

Clinical Trials Document-Specific XML tags:

• PUI number for clinical trial documents will be the original NCTxxxxxxxx number for that clinical trial (e.g. <itemid idtype="PUI">NCT00007904</itemid>). This also affects the files name in archives (i.e. LNCT00007904_2.xml in daily update folder)
• The database collection will be “Clinical Trial” (i.e. <dbcollection>CLINICAL TRIAL</dbcollection>).
• The citation type will be “ct” (i.e. <citation-type code="ct"/>).
• The source type will be “c” (i.e. <source type="c").
• The source title and abbreviated source title will be “clinical trials.gov” (e.g <sourcetitle>clinicaltrials.gov</sourcetitle>

                <sourcetitle-abbrev>clinicaltrials.gov</sourcetitle-abbrev>).

• The publisher name will be “clinicaltrials.gov” (i.e. <publishername>clinicaltrials.gov</publishername>).
• The <author-group> and <correspondence> elements will be absent for clinical trials.

Fixed Bugs

• Fixed an issue in PICO page where repetitive information was added in the term box.
• Fixed highlighting issue where it wasn’t displayed when index term contained a non-alphanumeric character.
• Fixed a bug where when trying to save a search with a reference search between quotes, it will create a corrupted saved search (ie. ‘#2’)

For additional information about Clinical Trials, please refer to the Clinical Trials FAQs.

We are excited to announce that we will be incorporating preprints from the Social Science Research Network (SSRN). This addition will enable us to offer a wider array of cutting-edge research findings that are critical to the evolving landscape of health and life sciences.

Focus Areas

In alignment with the scope of Embase, we will initially focus on two key subject areas from SSRN:

• Health Sciences: This area will cover a diverse range of topics pertinent to public health, healthcare delivery, and clinical practices.
• Life Sciences: This will encompass a variety of biological and neuroscience studies that are essential for advancing research in these fields.

Additional filter for SSRN in Journal Titles

The new SSRN repository can be filtered by limiting the selection to ‘SSRN’ Journal title:

Embase search engine update

From Tuesday October 15, 2024, Embase updated its search engine to the newest version of Elasticsearch (ES). With this move, performance, scalability and stability will be enhanced. It will also allow in the future to explore new exciting capabilities like data visualization with Embase.

We have extensively tested the new search engine update, but we recommend that you test your saved searches and email alerts to ensure they are functioning as expected. If you encounter any issues with your queries, please do not hesitate to contact us.

Update to the PubMed to Embase translation tool

We are excited to announce a new version of the PubMed to Embase translation tool. We have listened to your feedback and make the following changes:

Ability to add/remove terms in the translation box

Once the translation has been performed you will be able to add or remove terms inside of the translation box.

Ability to change the field codes of the translation

When translating non-indexed terms, you’ll be able to change the translated field codes. Just click on the term and select the field code of your choice from the side panel. Note: No field code multichoice is possible for the time being. You can do that by taking the query to the advanced search and modify it there.

Addition of proximity

It is now possible to translate PubMed proximity in the tool. For example, “hip pain”[title/abstract:~1] will be translated to ('hip' NEAR/2 'pain'):ti,ab,kw 

After the translation you can click on the translated term and add/remove field codes.

Please note that the terms inside the translation cannot be changed and if you want to change them you need to change them in the PubMed translation box and click on the “Translate” button.

Candidate terms workflow

We have implemented a candidate term workflow. When a MeSH term is mapped to an Emtree candidate term it’ll be properly highlighted. You’ll see a message explaining what a candidate term is and there will be a workflow to change the candidate term to any other Emtree term of your choice if needed.

Other new features

• Translation of & and | to AND and OR respectively.
• Better and more informative error messages.
• PubMed field code “affiliation” is now translated to :ad,ff (Searching in affiliation and address).

Bug fixing

• Terms with AND and OR inside the term are now properly translated.

“sprain and stains”[title] was translated to 'sprain' AND 'stains':ti. Now is translated to ‘sprain and strains’:ti

Feedback and Support:

We value your feedback and are committed to continuously improving your experience with Embase. If you encounter any issues, have suggestions, or need assistance with the PubMed translation feature, please reach out to our support team or use the feedback button at the bottom of the page.

Refreshed look of Clipboards: Now called lists

Clipboard is now called Temporary list and it’s been designed focusing on user experience. Temporary list can hold up to 5000 records and will be deleted once the session is terminated.

1. New design has the same features of the old design with a new refreshed look in accordance with the rest of Embase pages.
2. Pagination and number of records per page selection have been added to help users who have a large number of records. By splitting the results into multiple pages, it will ensure faster rendering and smoother navigation through the list records. This will save time and enhance the overall experience of using lists.

Release 1

Release 2

1. Saved search page: Simplified and more Intuitive

New saved search page focuses on improving user experience, folder organization, and manging saved searches in an efficient manner.

1. New design introduces filter which allows users to quickly locate specific searches by name. This feature adds convenience, enabling users to find the desired search or search group more easily without scrolling through a long list.
2. The new design will make it easier to identify the relationship between the saved search and the folder. Highlighting the folder names provides a visual cue that aids users in understanding where their searches will be saved. This prevents any confusion or accidental misplacement of searches.
3. Pagination has been added to help users who have a large number of saved searches. By splitting the results into multiple pages, it will ensure faster rendering and smoother navigation through the list of saved searches. This will save time and enhance the overall experience of using saved search page.

Creation of saved search

By default, the Private Folder and the Shared Folder only contain one folder, with the user’s name. The following options are available to add, rename or delete folders.

1. To create a folder, simply click on the '+ Create new folder' option, make sure that you have selected the desired parent folder where you want the new folder to be placed.
2. To edit/modify folder name and description users can select the ‘Edit’ option.
3. Selected folder can be deleted using the ‘Delete’ option.

Managing saved searches

The newest saved searches will be at the top, and older saved searches are at the bottom of the list. 

Some new features introduced are -

Filter by name

The filtering by name feature is advantageous for users who maintain their saved searches within a single folder. When users assign specific names to their saved searches, the filter by name functionality enables them to locate the desired saved search or group of saved searches more quickly and efficiently. This saves time by reducing effort in finding the exact search they need within their collection of saved searches.

Users also have the ability to choose multiple search groups, the results displayed will only show the selected searches.

Pagination

Adjusting the results per page

Alphabetic Sorting of Folders and Subfolders

The folder and sub folders will be sorted in alphabetical order.

Search details panel

To review more details of the saved search, please click on the search of interest. The search details panel will appear on the right side of the screen. All the actionable buttons like ‘Set email alert’, ‘Set RSS feed’ and ‘Edit’ are moved to the details panel.

Edit search window

2. Consistency between information displayed in email alert and record details page

The Email Alert and Record Details page provide essential information regarding the 'Country of Author' and 'Entry Date.' Here are the details regarding each:

• Country of Author: Refers to the correspondence address of the author
• Entry Date: The entry date indicates two significant milestones in the record's life cycle within Embase. Firstly, it reflects when the record was first introduced in Embase, which may occur when the article is in the "Article in Press" or "In Process" stage. Secondly, it denotes when the record was fully indexed, known as the "Full Record" stage.

Post this change, for the articles with multiple correspondence addresses, all of the corresponding countries will be included in both the record details page and email alert.

For e.g L2022640464

3. Improving stability of Embase API

Embase API is not recommended for large volumes of data downloads. Large volumes of data download cause instability and performance issue. Hence in order to give all users an equal opportunity to use search on Embase API, we have established limits to 500k on how much data can be downloaded.

Bugs Fixed

1. Issue with Clipboard export fixed. When records are added from multiple searches into the clipboard, on export incomplete result are downloaded. This issue has been fixed.
2. Editing Search Line in Results page always showed blank (-) while using the test query feature. This issue has been fixed

1. Laying the foundation for COUNTER compliance

Embase is aiming to be COUNTER compliant in 2023. As the first step towards achieving this goal we have defined and implemented tracking for the COUNTER metrics. Once the reports are audited, we will host the customer facing reports on EPIC system. Please watch this space for more information on timelines on availability of Embase COUNTER compliant reports.

2. Synonym list on Emtree page updated

Previously, the search created using the synonym list in PICO vs search created using the synonym list in Emtree resulted in mismatch number of results. It was because the searched term was not part of the synonym list in Emtree.

In this release we have added the searched term in the synonym list of Emtree for result consistency.

Bugs Fixed

1. Fixed Embase session interruptions caused due to third party plugins like RSS reader.
2. Missing GMDN information added in Emtree for the term ‘Sjoegren's antibody test kit’.
3. User were unable to save an alert with search query of size 8k characters This issue has been fixed.

Easy to use Emtree page

1. Split view display allows easier navigation

   

   

   • New Emtree page design with a split view and with a new tree behaviour which allows an easier navigation.
   • Addition of the option to add a /syn modifier that maps, explodes, and searches your term adding all the available synonyms as free text in all fields.
   • Ability to copy synonyms either with an OR operator between the terms to use them as part of your search or as a list for your reporting purposes.
   • Split view to see all the time the Emtree on the left panel with an easy navigation system and information regarding synonyms, Dorlands Dictionary, GMDN information and CAS registry number.
   • CAS registry numbers now have a link to Reaxys and PubChem.
   • When you select the term, Embase will automatically detect the type of term it is and suggest where to send the search (Disease, Drug, Device or Advanced). Now user can change that suggestion if they wish so.

    

   You can now extend your search using different modifications to search the term directly, send it to Drug, Disease, Device, Advanced search, or to the Query Builder:

   • /mj (Focuses your search to records where your search term is indexed as "major focus")
   • /de (Searches your term or maps to the preferred Emtree term (if your term is a synonym in Embase). No narrower terms are added.
   • /exp/mj (Searches your term (or maps to the preferred Emtree term) and related narrower or narrower terms but where the terms are indexed as "major focus")
   • /exp (Searches your term (or maps to the preferred Emtree term) and related narrower or children terms)
   • /br (Maps, explodes and searches your term as free text in all fields)
   • /syn (Maps, explodes and searches your term adding all the available synonyms as free text in all fields)

    

   Copy the synonyms of terms in two different ways:

   • Click on “Copy” button to copy all the synonyms with the OR operator between them. Useful when you want to extend your search to all the synonyms.
   • Select all the synonyms by click and dragging and do a copy/paste action will paste the synonyms as a list.

    

   

   Unified the behaviour of the pages that have Emtree in them

   

   

   • Clicking on the term will send the word into the search bar (PICO or Medical Device pages) or in the right-side panel with more information (Emtree page):
   • Clicking on the circle at the left of the term will open the terms under the selected term:
   • If there’s no circle next to the term but just a black dot means that that term does not have any narrower terms.

2. Linking of preprint to related published article

   Post the inclusion of preprint records in Embase, we received feedback from the users to provide linking between preprints and its related published article. We have added indication to the results page, and the email alert of the existence of the related publication.

   2. Editing a saved search will not result in changing the names of all saved searches
   3. The search containing field code ‘df’ and ‘dn’ when combined with the other searches resulted in errors. This issue has been fixed.

1. Narrowing search results made easy in PICO form

We have brought the PICO search form front and center and moved the Emtree panel to the right side of the form. You now have the option to apply limits directly in the PICO form.

You can build focused questions using 5 elements of the PICO search (Patient, Intervention, Comparison/Control, Outcome, Study type). This search form will combine terms with an OR operator between each search term within the same element and an AND operator to combine terms of different elements.

You can directly type into these fields in the PICO search form or find the best term in the Emtree panel on the right. The added term will be highlighted blue if they are not preferred terms in Emtree and orange if they are. Use ‘Add # synonyms’ to see and add or remove synonyms for your search term.

At the top of the screen, you can choose from 4 different search strategy options from the drop down. These options can also be selected from the drop-down arrow next to each search term:

• /mj (Major Focus): Focuses your search to record where your search term is indexed as major focus.
• /de (Index term): Searches your terms or maps to the preferred Emtree term (if your term is a synonym in Emtree).
• /exp (Explosion): Searches your term (or maps to the preferred Emtree term) and related narrower or children terms.
• /br (As broad as possible): Maps, explodes and searches your term as free text in all fields.

You can also clear fields or remove fields or reset the form entirely at any time.

Apply limits directly in the PICO form -

You can narrow your search using the Limit to option. You can search for records within a certain publication year or for records added to Embase in certain period.

You can view the entire query by clicking on the ‘Display full query’ option. It provides insight on how Embase interprets your search query. Query can be copied easily by using the ‘Copy query’ button.

Easy to use ‘Quick search page’

We have simplified our quick search page to make it more intuitive and user friendly.

To access the Quick search, go to the homepage. In this search form you will now be presented with a single search box with an option to add multiple search fields by using the ‘Add field ‘ button.

You can add the search terms or phrase of interest into the provided search box. As soon as the term is added, Emtree will automatically suggest a preferred term that would encompass not just the entered term but also the linked synonyms. Hence using the preferred term suggested by Emtree ensures that no information is missed. On click of ‘Show results‘ button or by pressing ‘Enter‘ Embase will perform a broad search by default. It will automatically convert this to explosion plus free text search.

Improved support for ISSN field

ISSN field (:is) will now support entries with space and hyphens.

For eg. All the following variants will provide the same result hits

'10292659':is
'1029 2659':is
