Recently, the MeSH database, the controlled vocabulary by which articles in PubMed are indexed, was changed.
An autocomplete feature, a dropdown list of suggested terms, was added to the main MeSH search page.
The Search Builder within the MeSH database has been moved from the top of the page to the right side. Select your term from the Summary page (the list of results from your search in the MeSH database), then click “Add to search builder”. When you’ve added all the terms you need and selected the correct Boolean operators, click “Search PubMed”.
To add subheadings to MeSH terms, simply click on the MeSH term on the Summary (or main) page, then check the subheading.
