How do I use the query builder feature in Quick Search? (Alpha)
Last updated on December 03, 2025
You can broaden your Engineering Village search queries using the new query builder feature on the Quick Search page. The query builder has been designed to interpret natural language, Boolean expressions, and simple keyword queries. This new feature is a powerful application that uses Engineering Village AI (artificial intelligence) to help you efficiently broaden your search queries.
The query builder feature aims to streamline the research process and facilitate knowledge discovery by building high-precision Engineering Village Boolean, proximity, and topic-exclusion search queries. This feature suggests expanded search terms tailored to your own unique keywords, natural language, and expanded Boolean queries. You can execute these expanded keyword queries directly or choose to disregard them and continue with your own input.
Simple keywords
The query builder augments simple keywords with commonly used synonyms, enriching the query and enabling much more comprehensive, precise results through expanded search syntax, such as exact phrases, proximity operators, and specific exclusion filters, where appropriate.
Expanded Boolean output
The query builder builds search queries from input containing ‘AND,’ ‘OR,’ and ‘NOT’ Boolean operators.
Natural language
The query builder constructs search queries from natural language instructions and questions.
Refer to the query builder examples section of this FAQ for the various types of search queries that are supported by this feature.
- Navigate to the Quick Search page.
- Select the database(s) you want to include in your search query. The database name(s) you selected (or the number of databases if you selected more than two) are displayed on the page.
- From the ‘Search within’ dropdown box, select the field that you want to use for your query.
- The ‘All fields’ option is the default.
- From the ‘Search documents’ text box, enter your search term(s) as desired.
Click the Artificial Intelligence (AI) icon box.

The ‘Use expanded keywords’ pop-up window opens.
- Click ‘Add keywords’ to accept the expanded keyword query suggestion OR
- Click ‘Decline’ to reject the expanded keyword query suggestion OR
- Click the ‘X’ to close the pop-up window.
- If you accept the query suggestion, it will replace your original search query and display in the ‘Search documents’ text box.
- You may keep the search query as is or edit it.
- If desired, add more search fields.
- Repeat steps 4 through 8 to use the expanded query search feature.
- If desired, add a year range. Select the preferred publication year range.
- Click ‘Search’ to run your search query. If you accepted the suggested keyword(s), your search query results include the expanded keywords.
Important notes:
- To enable the query builder feature, you must enter at least one search term in the ‘Search documents’ box.
- You may use simple keywords, natural language text, and/or the Boolean connectors ‘AND,’ ‘OR,’ and ‘NOT’ between the search terms if desired.
- When using the query builder feature (by accepting the suggested keyword query suggestion), a maximum of 500 characters, including spaces, can be entered into the ‘Search documents’ text input box. However, the 500-character limit in this text input box only applies when using the query builder feature and not when entering a regular Quick search query without using this specific feature.
- This query builder feature is designed to broaden Quick Searches by suggesting additional keywords to supplement your individual search terms and natural language queries. If you prefer to use advanced Boolean logic in your search queries, use Expert Search.

Although Engineering Village AI relies on trustworthy data, inaccurate, distorted, or objectionable keywords may be suggested as expanded keywords. To protect the privacy and integrity of your research, avoid entering personal, confidential, or sensitive information into the query builder search feature.
