google Search Appliance Compatible API
Fess also provides an API that returns search results in google Search Appliance (GSA) compatible XML format. For details about the XML format, please refer to the GSA Official Documentation.
Configuration
To enable the google Search Appliance Compatible API, add web.api.gsa=true to system.properties.
Request
By sending a request to Fess like http://localhost:8080/gsa/?q=search_term, you can receive search results in GSA-compatible XML format. The request parameters that can be specified are the same as the JSON Response Search API.
