Content provider ProQuest Dialog offers a medical synonym feature which allows users to include related medical terms in their searches and alerts. For example, if the user is searching for information on headaches, ProQuest Dialog will also include such synonyms as cephalalgia, encephalalgia, and encephalodynia in the search. This feature, available in all ProQuest Dialog databases, is handy for intellectual property searchers and helps investigators locate content that can be buried in medical or legal language.
