What Is the Thesaurus?
Example: When the word knowledge is added to the thesaurus as a synonym of intelligence, a query for knowledge automatically searches for knowledge OR intelligence (although only knowledge appears in the search box).
The CES index thesaurus is originally empty and must be populated by your Coveo administrator (see Adding Thesaurus Entries From the Administration Tool) or (see Creating or Modifying a Thesaurus XML File).
By default, the thesaurus applies only to free text queries. A Coveo administrator can also apply it to field queries (see Importing a Thesaurus XML File in CES).
CES 7.0.8225– (March 2016) The thesaurus is deactivated when a query contains the NOT or the NEAR operator.
Example: When the word bob is set as a synonym of robert in the thesaurus, a query for bob becomes bob OR robert. However, when the query is bob NOT arthur, the query is not expanded and remains bob NOT arthur.
