Processing the Request and Response

The form handlers include three properties for specifying components for preprocessing the search request and postprocessing the response:

searchRequestProcessors
An array of Nucleus components for preprocessing the search request before it is submitted. Each component in the array must be of a class that implements the atg.search.formhandlers.SearchRequestProcessor interface.

searchResponseProcessors
An array of Nucleus components for postprocessing the search response after it is received. Each component in the array must be of a class that implements the atg.search.formhandlers.SearchResponseProcessor interface.

searchRedirectProcessors
An array of Nucleus components for determining the URL to redirect to, depending on the search results. Each component in the array must be of a class that implements the atg.search.formhandlers.SearchRedirectProcessor interface.

Note that the /atg/commerce/search/catalog/QueryFormHandler component is configured to use the /atg/search/repository/FacetSearchTools component as a request preprocessor and postprocessor. This component is of class atg.commerce.search.refinement.custom.CustomCatalogFacetSearchTools, which implements all three interfaces listed above.
