# Monitor Terms in the Data Index

(Available for the IDOL Content and IDOL Agentstore components.)

The Terms tab in the Performance page displays information about terms in the indexed data. The `TermGetAll` and `TermGetInfo` actions return this information. For information about these actions, see the IDOL Server Reference.

By default, the tab contains a graph displaying the number of documents that terms occur in. Hover over the bars to display the exact values. Clicking on a bar displays a table containing details of the stemmed terms that occur in the selected number of documents.

Click Refresh to update the information at any time.

For details about the information displayed in the tables in the Terms tab, see the following topics:

- Term Totals
- Term Averages
- Stemmed Terms
