What are MeSH terms and should I use them in my BioMail search parameters?
MeSH terms are special indexing terms at PubMed. They may greatly enhance the search power of your queries, even if you don’t use MeSH-terms explicitly. Newly added papers (labeled [PubMed – in process]) have not been indexed with MeSH terms yet. If you want to search using MeSH terms, select “Indexed references only”.
