# Create Query Manipulation Server Rules

The Promotion Agentstore component stores QMS rules in a similar way to the way in which IDOL Server stores agents and categories.

The QMS rules documents must contain text that defines the queries that they affect. They also define which actions are performed on the queries, and the results for any transformations. For some QMS rules you can also apply a schedule, so that the rule is active only at certain times.

You create QMS rules as IDX documents, which you index into the Promotion Agentstore. If you do not use QMS with IDOL Data Admin, you must manually create IDX documents and index them. For details on how to manually create an IDX document, refer to the IDOL Server Administration Guide.
