The next step of search processing is to apply constraints that were entered along with the request. Constraints can include the following:
Site, catalog, category, or other property-based constraints—See the Constraining Queries chapter of this guide
Operators such as quote marks and the ! symbol—See the User-Entered Operators chapter of this guide
Query rules—See the ATG Search Administration Guide
Search Merchandising rank configurations—See the Search Merchandising chapter of this guide
The constraints are processed and added to the query information.
