Thesaurus entries provide a means to account for alternate forms of a user's query.
You can open the Thesaurus page from Search Tools on the application Home page. On the Thesaurus page, you create the synonyms that capture other ways of expressing queries relevant to your application. These entries provide concept-level mappings between words and phrases.
You can add two kinds of entries to your thesaurus:
One-way thesaurus entries establish an equivalence between words or phrases that applies in a single direction only. For example, you could define a one-way mapping so that all queries for computer would also return matches containing laptop, but queries for laptop would not return results for the more general computer. You can add an unlimited number of synonyms to a one-way entry, and the application expands the query to search for each search term with the same one-way relationship.
Multi-way thesaurus entries establish a mutual equivalence relationship between words or phrases. For example, an equivalence might specify that the phrase notebook is interchangeable with the phrase laptop.
