Untagged terms that are entered in the search box are matched (in this order) against a Subject translation table (including MeSH (Medical Subject Headings) , a Journals translation table, the Author index, and an Investigator (Collaborator) index.
When a match is found for a term or phrase in a translation table the mapping process is complete and does not continue on to the next translation table.
PubMed allows users to search with text words, similar to a Google search. Automatic Term Mapping (ATM) is used to identify results when searching by text word(s).
Use the single citation matcher to quickly find a citation by journal title, author, or article title.
How do I search for phrases?
Using double quotation marks allows you to search for a specific phrase. Doing so means the database searches all fields for your phrase. In the image below, notice how differently PubMed interprets the search with and without the use of quotation marks.
