Overview of the Search Results Page
After you have entered search terms into one or more search fields and clicked on one of the search buttons, the search results will appear on a new screen below the search box.
The List tab is the default view for search results. This list view shows the most relevant study records for your search terms in a table format.
You can change how the search results are displayed in the following ways:
- Click on the By Topic tab to browse your search results grouped by various topics, using categories or alphabetical lists
- Click on the On Map tab to view and browse your search results by location
- Click on the Search Details tab to view recognized terms and synonyms and related terms:
- Under Terms and Synonyms Searched, view a table showing all query terms and synonyms for your search terms. For example, the term "skin neoplasm" is a synonym for "skin cancer."
- Under Related Terms, click on any term to refine your search. For example, click on education after conducting a search on the term "diabetes" to find studies related to diabetes education.
Use the Filters found on the left side of the Search Results page to narrow or change the list of studies shown in search results. Click on the box next to each filter you'd like to apply (or remove). After making the selection(s), click the Apply button. For example, mark the Recruiting checkbox and click the Apply button to see only studies that are open and recruiting new participants.
