Phrase Searching (continued)
- Using quotes, search tags, hypenation or truncation instructs PubMed to bypass automatic term mapping. Instead PubMed looks for the phrase in its Index of
searchable terms. If the phrase is in the Index, PubMed will retrieve
citations that contain the phrase.
- PubMed may fail to find a phrase because it is not in the Index.
- Your phrase may actually appear in citation and abstract data, but may not be in the Index. If this is the case, the double quotes are ignored and
the phrase is processed using Automatic Term Mapping.
Note: Try your search with and without quotes, hypenation and truncation and compare your results.
For more detail, see the Technical Bulletin article Skill Kit: Searching for Phrases in PubMed.
