Advanced Search Builder

PubMed includes an Advanced Search Builder to help users:

• Search for terms in a specific field or "All Fields"
• Combine searches and build large, complex search strings
• View how each query was translated by PubMed
• Compare the number of results for different queries

You can use the Boolean operators AND, OR, and NOT to create specific searches in the query box.

Also, your current PubMed session’s search history is saved for your reference and includes additional information about how PubMed processed your search under "Details." Your search history will expire after eight hours of inactivity.

You can locate the Advanced Search Builder option on any PubMed page under the search bar.

You can also link to the Advanced Search Builder by clicking "Advanced Search" under "Find" on the PubMed homepage.

Understanding all that the Advanced Search Builder has to offer goes beyond the scope of this module, but we recommend that frequent PubMed searchers become comfortable with using the Advanced Search Builder to build searches that are more precise.
