Advanced Searching

The Advanced link provides two options to refine a search:

  • Use the PubMed Advanced Search Builder to create a search using AND, OR, or NOT.
  • Apply a specific field to your term by using the dropdown menu.

You may also use the Show index list  to see your search history, which tracks and numbers search statements. Click on the numbered link to view a menu of options to combine search statements into a new search with AND, OR, or NOT. The search may also be run, deleted, examined in Details, or saved in My NCBI.
