How PubMed Performs Searches
PubMed indexes articles with controlled vocabulary called MeSH (Medical Subject Headings). The search engine uses automatic term mapping to map your keyword search terms(s) to the appropriate MeSH term(s), journal titles, a phrase list, or an author index in that order. If the term is not matched, it is searched in all fields.
You can see the MeSH terms for an article once you click on an article title from a results list. To start searching, just enter your keyword search term(s) in the basic search box. You can you see how your search was indexed by MeSH terms under the "MeSH Terms" area by selecting it as noted in red below. Advanced search and MeSH search options are also available. See tutorials in the left sidebar on this page or view the Searching PubMed with MeSH Terms page of this guide for Basic and MeSH searches.
