New PubMed Feature: Best Match

Earlier this year PubMed released a new way of sorting search results: Best Match. It replaces the Relevance Sort feature that was previously available. You can use Best Match by clicking on the “Sort by” link on the top of a PubMed results screen and selecting “Best Match.”


Best Match








Best Match is a search algorithm that uses machine learning to attempt to locate the most relevant articles. Here are a few things to keep in mind when using the Best Match feature in PubMed:

  • The number of results listed might change when you sort by Best Match.
  • Only the first 10,000 results will display (switching to any other “sort by” option will allow you to view full search results).
  • The Search Details box on the right side of the screen changes to Best Match Search Information.
