Why Search with (MeSH)
When searching a National Library of medicine database (Medline), why is it preferable to use Medical Subject Heading (MESH) instead of a natural language term (textword)?
A textword search only retrieves articles containing exact word matches in the title or abstract of an article.
Using a MeSH term retrieves articles about the subject, and does not rely only on an exact word match.
Synonyms are automatically included when MeSH terms are used to search.
Searching for leg as a textword retrieves only articles containing the word leg.
Searching for leg as a MeSH term retrieves leg, ankle, foot, hip, knee, thigh.
