# AgentBoolean Fields

QMS rules match queries by using AgentBoolean and FieldText expressions. To optimize this matching process, you can configure the Promotion Agentstore to cache the values of the QMS rules fields that store the expressions.

For details about AgentBoolean fields, refer to the IDOL Server Administration Guide.

To configure AgentBoolean fields

1. Open the Promotion Agentstore configuration file in a text editor.

2. In the `[Server]` section, add or edit the following configuration parameters:

       [Server]
       AgentBooleanCacheField=*/QMSAGENTBOOL
       FieldTextCacheField=*/QMSFIELDTEXT

3. Restart the Promotion Agentstore for your changes to take effect.

NOTE: If you change these settings after you index rules into Promotion Agentstore, you must re-index the rules.
