The Google Search Appliance accepts search requests as input, and returns search results as output.

Search users typically use HTML forms displayed in a web browser to make these requests, but other applications can also send search requests by making appropriate HTTP requests. The search request format and options available are described in detail in the Request Format section.
Search results, the output, are returned in either HTML or XML formats, as specified in the search request.
