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).
Notes:
-
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.
