Importing a Thesaurus XML File in CES

Once a custom thesaurus file has been created, you need to import it in CES to activate its content for query expansion.

To import a thesaurus file

  1. On the Coveo server, access the Administration Tool (see Opening the Administration Tool).

  2. In the Administration Tool, select Index > Thesaurus.

  3. In the Thesaurus page:

    1. In the navigation panel on the left, click General.

    2. In the Thesaurus XML File box, enter the path of the new thesaurus file.

      The recommended folder is [Index_Path]\Config.

      Example: D:\CES7\Config\MyThesaurus.xml

    3. In the Option section, select the Apply thesaurus to field queries check box when you want the thesaurus entries to also expand field queries (see What Are Field Queries and Free Text Queries?).

      Note: By default, the thesaurus applies only to free text queries. In general, it does not make sense to apply the thesaurus to field queries because the purpose of field queries it to refine searches; whereas, the purpose of the thesaurus is to expand them. You may however encounter situations where it is desirable to also apply the thesaurus to field queries.

    4. Click Apply Changes.

      The thesaurus is loaded when the CES service starts.

  4. You can refresh the thesaurus file without restarting the service (see Refreshing the Thesaurus).
