Endeca provides a mechanism for filtering the records returned by a query, based on the values of record properties. For example, for a multisite application, you can use record filters to control which sites a query returns results for. To return results for only a single site, you use a filter to exclude all records except the ones that include a product.siteId property whose value is the ID of the desired site.

This chapter discusses ATG classes you can use to build and apply Endeca record filters.
