Spell Check

Spell check feature, example of hemorhage

Spell check suggests alternative spellings for search terms that include misspellings. Results from a search with the closest common word will display, or an option to link to an alternative spelling to provide users with an easy way to retrieve results for untagged words that are misspelled.

Terms entered with a search tag (e.g., [mh]; [majr]; [tw]) will not generate alternative spellings.


  • The alternative spellings are not based on a dictionary but rather the frequency with which a term appears in PubMed.

  • The spell checking function will not display an alternative spelling for misspellings that have a high frequency of occurrence in PubMed or for terms with numbers or fewer than 5 characters.

  • The feature works best for terms with multiple words.
