## Migration From Other Enterprise Search Systems

### Google Search Appliance (GSA) / Google Mini

Fess provides a [Google Search Appliance](https://enterprise.google.com/search/products/gsa.html) (GSA) compatible API. To enable this API, set `web.api.gsa=true` to system.properties. This will enable an enpoint at `<Fess Server Name>:8080/gsa`. When a search query is sent to `<Fess Server Name>:8080/gsa/?q=QUERY`, a GSA compatible response will be returned

 Plugins should avoid these classes and be updated to use only Maven3 dependencies (and require Maven3): see
 {{{https://cwiki.apache.org/confluence/display/MAVEN/Plugin+migration+to+Maven3+dependencies} Plugin migration to Maven3 dependencies}}

## Data Store

Currently, Fess supports crawling the following [storage locations and APIs](https://fess.codelibs.org/14.17/admin/dataconfig-guide.html):

## Datenspeicher

Derzeit unterstützt Fess das Crawlen der folgenden [Speicherorte und APIs](https://fess.codelibs.org/14.17/admin/dataconfig-guide.html):

// and format-xl.go for details.

// fields of this struct and deal with related migration.

	// Version of the format config.
	Version string `json:"version"`
	// Format indicates the backend format type, supports two values 'xl' and 'fs'.
