Embase Release Notes
Last updated on November 26, 2025
Please find below the latest Embase release notes:
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
- Resolved issues affecting the CITE button functionality
- 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.

- Use of tables in system responses when appropriate
- Improved follow-up prompt to avoid previous context bleeding into the rephrased follow-up question
- Improved retry prompts to avoid cases of zero results or syntax error
- Option to limit search to clinicaltrials.gov in query translation
- Improved detection of "results only" case where no natural-language summary should be produced
Moreover, the prompt and gold answers for the Comprehensiveness metric were completely rewritten to generate more meaningful evaluation results.
Changes in Embase AI functionality
- Summary will now include up to 10 references instead of 5.
- Ability to export the references used for the summary in different formats.
- Embase AI tab visible for non-registered users to increase its internal awareness.
- To increase its visibility, we have added a “New” sign near to the tab name.
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
Results filters on the left side of the page
- Sources – Limit your content selection to only clinical trials by using the new ‘Clinical trials’ database collection option
- Publication types – Limit your content selection by using the new ‘Clinical trial’ option
- Journal titles – Limit your content selection by using the new ‘clinicaltrials.gov’ option
Using the query syntax to include or exclude clinical trials
Filter by Database Collection:
- Use NOT 'clinical trial':dtype to exclude all documents from the clinical trial database collection
Results may include other content like articles citing clinical trials or preprints relating to clinical trials, as long as these documents are NOT of the database collection type "clinical trial".
- Use AND 'clinical trial':dtype to get results that ONLY contain documents from the clinical trial database collection.
Filter by Publication Type:
- Use NOT 'clinical trial'/it to exclude all documents of the publication type "clinical trial".
Results may include other content like articles citing clinical trials or preprints relating to clinical trials, as long as these documents are NOT of the publication type "clinical trial".
- Use AND 'clinical trial'/it to get results that ONLY contain documents of the publication type "clinical trial".
Filter by Journal Title:
- Use NOT 'clinicaltrials.gov'/jt to exclude all documents under the journal title "clinicaltrials.gov".
- 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 16th 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 5th 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 16th 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
25th March 2025 - technical release that will result in filters for clinical trial content to appear on Embase.com - however, there will be no content associated yet with these filters
5th May 2025 - clinical trials content will start to be added
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.
- New design has the same features of the old design with a new refreshed look in accordance with the rest of Embase pages.
- 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
Improved search precision with the ‘controlled clinical trial’ EBM limit.
The "Controlled Clinical Trial" EBM limit can be accessed from the Results page, Quick Search, Advanced Search, Drug Search, Disease Search, and Device Search forms.
Controlled clinical trial limit pertains to original clinical trial reports incorporating a control group (e.g., placebo, sham, or no treatment, standard intervention) for comparison with the experimental intervention.
With the updated definition of the limit, the search will only pick the records where the controlled clinical trial has been duly recognized and indexed. The retrieved records will be considerably fewer than before, but will have a higher level of precision.
- Old definition
[controlled clinical trial]/lim → 'controlled study'/exp AND 'clinical trial'/exp - New definition
[controlled clinical trial]/lim → 'controlled clinical trial'/de
Editing email alerts
When creating an alert, if a user accidentally includes spaces between miltiple email addresses, our system failed to validate the recipient information.This created an issue when the user wished to edit the saved email alert.
To address this, we have implemented an automatic space-trimming to ensure that the recipient information is saved correctly and it does not cause issues while editing the saved email alert.
Longer Embase session
When using Embase.com, if a user perform a search and leave the site and returns after 30 minutes, user will experience an automatic implicit relogin if they have the 'Stay signed in' option selected. However, users who don’t have this option checked will need to enter their credentials and log in again.
In this release, we have extended the user session from 30 minutes to 2 hours, even for users who haven't chosen the 'Stay signed in' option.
This enhancement ensures that the session remains active up to 2 hours, which means user won’t need to re-login if the idle time is less than 2 hours.
Bugs Fixed
Correction to the unknown database collection in the Embase
Content within Embase that intersects with the nursing collection is marked with the 'NURSING' tag.
Changes will be observed in -
XML exported file
Old → <dbcollection code="NURSNG">unknown</dbcollection>
New → <dbcollection code="NURSNG">NURSING</dbcollection>Results page
In addition to Embase, will find article also marked as ‘NURSING’ for the overlapping articles
Record details page
Source of indexing will also include NURSING for the overlapping articles.
- Highlighting was breaking for index terms containing consecutive spaces, resulting in search failures. To address this, we have implemented a normalization process for these index terms before applying highlighting. As a result, searches will now run without any problems.
Release 2
Why do you change the indexing?
We need our indexing technology to be more flexible and modular for future innovation (new content types, new information extracted from existing content).
What changes exactly?
We are improving the technology we use for the automatic indexing step of processing Embase’s records. For this, we are switching to a different technology: SciBite with its named entity recognition (NER) and extraction engine TERMite.
This technological improvement is the first step to providing our customers with improved indexing quality. This enhancement has been released on November 20th.
What stays as it used to?
- No change in format.
- Indexing Embase involves a two-step process for most articles (preconditions are explained in our indexing guideline): the first step is automatic indexing on the title and abstract of the Embase article. Then, after verification the preconditions, the next step is an in-depth manual indexing based on the content in the full text, usually available a few weeks later. This will continue to be done as it always has been, and as documented in this FAQ.
- This new technology will deliver a similar indexing quality (recall and precision) compared to our previous process which also leverages Emtree terms to automatically index content, making the Embase content available as soon as possible to customers. You will not need to make any changes to your workflow. In a comparable way to any time our indexing is updated (e.g., during the 3x/year Emtree releases), we recommend reviewing saved search/email alert queries and update them if needed.
How does this look like concretely?
Here are two examples where you can see that there can be slight differences with the new technology indexing more terms, different terms, or less terms.
What will happen in the future?
The next step will be for the initial indexing (on titles and abstracts) to be improved and complemented with medical devices, tradenames, and manufacturers from the full text article. This will enable our customers to retrieve the most relevant records sooner to improve precision and recall at an earlier stage while manual indexing is still performed in a second step. This is an improvement that our medical devices customers have been requesting. On a long term, the new technology will also allow the processing of new content types (new sources or new extracted information), which will provide further advancements in the upcoming years.
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.
- 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.
- 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.
- 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
Naming the search is optional and can only be done when saving the search. Names are limited to 75 characters. |
|
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.
- 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.
- To edit/modify folder name and description users can select the ‘Edit’ option.
- 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
Allows easy navigation through large number of results set. Faster loading of the results, enables quick access to specific sections within a larger number of saved searches. |
|
Adjusting the results per page
To adjust the number of searches displayed per page, simply click on the dropdown labeled "Results per page." You can choose to display 20, 50, 200, or 500 searches per page. For instance, if you choose 20, the first page will show the 20 most recently saved searches. |
|
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
This dedicated edit window allows users to review and modify their search easily. |
|
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
Old | New | ||
Email alert | Country of author, in case multiple correspondence address is available | United States, Germany | United States, Germany |
Entry date | 2023-02-17 (Full record)2023-03-08 (Full record), 2023-02-17 (Article in Press/In process) | 2023-03-08 (Full record), 2023-02-17 (Article in Press/In process) | |
Record details page | Country of author | United States | United States, Germany |
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
- 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.
- 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
- Fixed Embase session interruptions caused due to third party plugins like RSS reader.
- Missing GMDN information added in Emtree for the term ‘Sjoegren's antibody test kit’.
- User were unable to save an alert with search query of size 8k characters This issue has been fixed.
Easy to use Emtree page
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)

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.
2. Evidence based medicine limits updated
For better accuracy we have updated the definition of ‘Cochrane review’ and the ‘Controlled Clinical trial’ EBM limits to the following.
Name | Old mapping | New mapping |
Cochrane review | ‘1469493X’:is | (‘1469493X’:is OR ‘14651858’:is) |
Controlled Clinical Trial | 'controlled study'/exp AND 'clinical trial'/exp | 'controlled clinical trial'/de |
3. Allow searching by date range with the publication date field code (pd)
We will now support searching by date ranges using the Publication date field code.
For e.g In order to retrieve all the literature associated to the term 'injury' which was published between 1st March 2021 and 31st August 2021.
You can carry out the search ('injury'/exp OR 'injury') AND [01-03-2021 to 31-08-2021]/pd.
4. Record details page to display information more clinical trial registries

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
'1029-2659':is
