You can configure Oracle ATG Web Commerce Search to cache entire user queries and their responses. This can improve performance by removing load from the search engines, and is most useful when many users are doing browse-type searches (such as faceted navigation) that result in repeated identical queries.

The cache stores the environment name, the query XML, and the response XML. By default, the cache stores the most recently used queries and their responses in memory, while older responses are stored on disk.

Any Oracle ATG Web Commerce instance running the DAF.Search.Routing module can cache search data; caches are created as needed, with one cache per search environment.
