PubMed automatically searches for phrases during Automatic Term Mapping.
Do NOT use quotes until you first try your search without them.
If you determine that PubMed processed your search differently than you would like [Show Me] and you want to force a phrase search, you can do so by:
- Enclosing the phrase in double quotes:
"fecal transplant" [Show Me]
Note: The absence of a search tag indicates the search should be conducted in All Fields.
- Entering the phrase with a search tag:
robotic surgery [tw]
