# Query Manipulation Server Rules Overview

QMS rules contain the information that QMS uses to modify user queries. You store the rules in the Promotion Agentstore.

Promotion Agentstore is an IDOL Server Content component. It stores rules in the same way that the Content component stores documents, or the Agentstore components stores agents and categories.

QMS rules are IDX or XML documents that contain the fields that the Promotion Agentstore and QMS need to find and apply rules. You can create QMS rules in IDOL Data Admin, or you can create the IDX documents manually and index them into the Promotion Agentstore.

For details of how to use QMS in IDOL Data Admin, refer to the IDOL Data Admin User Guide.

You can create the following types of QMS rules:

- Static promotions. Return a specified document or set of documents as a promotion.
- Dynamic promotions. Return the results of a query as a promotion.
- Synonyms. Modify the query with synonymous terms.
- Whitelists. Modify the query to remove terms that do not occur in the whitelist.
- Blacklists. Modify the query to remove terms that occur in the blacklist.
- Boost rules. Add extra query FieldText.
- Cardinal placements. Add a document to a specified position in the results list.
- Parametric cardinal placements. Add a parametric value to a specified position in the results list.
