Question: What does major mean in a Dialog thesaurus?
Answer: This option, when selected, will search the selected term within the thesaurus. Major is assigned to a term (by the Embase & Medline indexers) to denote that this describes what the major thrust of an article is. Using “Drug Therapy” as the example:MJMESH.exact(“Drug Therapy”) or for Embase MJEMB.exact(“Drug Therapy”)An example record retrieved is:Title: Efficacy and safety of acupuncture combined with western medicine for anxiety: A systematic review protocolAs you can see, for every term that has "major" assigned to it, (major) is listed at the end of that term.
Unfortunately, when you instruct the Embase/Medline thesaurui to restrict to “Major”, it will only search for terms limited to that particular designation.
