Microsoft Exam AI-102 Topic 1 Question 27 Discussion

Within a search service, synonym maps are a global resource that associate equivalent terms, expanding the scope of a query without the user having to actually provide the term. For example, assuming 'dog', 'canine', and 'puppy' are mapped synonyms, a query on 'canine' will match on a document containing 'dog'.

Create synonyms: A synonym map is an asset that can be created once and used by many indexes.
