MeSH Headings [MH]

The MeSH Database, Limits, and Preview/Index can also be used to select MeSH headings for your search. Alternatively, you may use MeSH search field qualifiers:

• [mh] to search a MeSH heading (e.g., thromboembolism[mh]).
  
  
• [majr] to search a MeSH heading which is a major topic of an article (e.g., thromboembolism[majr]).
  
  
• [mh:noexp] to search a MeSH heading and turn off the automatic EXPLODE (e.g., thromboembolism[mh:noexp]).
  
  
• [majr:noexp] to search a MeSH heading as a major topic and turn off the automatic EXPLODE (e.g., thromboembolism[majr:noexp]).
  
  
• Searching with MeSH tags will exclude In Process and publisher-supplied citations as they are not indexed with MeSH.
  
  
• PubMed will not supplement your search with Text Words if searching with MeSH tags.

To see how PubMed translates a search term with the [mh] field tag, go to Details. [Show Me] PubMed searched for the term as a MeSH heading only.
