PubMed Search Algorithms

PubMed uses multiple state-of-the-art machine-learning algorithms to decipher your keywords and make the best search possible. For most basic searches, you will not need to use quotations around phrases or Boolean operators. Features include:

  • Best Match sort order places the most relevant citations at the top of your results list.
  • Automatic term mapping applies alternative terms.
  • Advanced Character mapping allows the use of characters in search strings
  • Spell-checking
  • Predictive keywords try to anticipate your keywords as you type.
  • Citation sensor helps find known articles by deciphering terms that may contain characteristics of citation searching, Ex. author names, journal titles (full or abbreviated), publication dates, and article titles.
  • MeSH (Medical Subject Headings) - a searchable, mapped controlled vocabulary thesaurus
