## 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 For the more details, see the implementation code in [GsaApiManager](/src/main/java/org/codelibs/fess/api/gsa/GsaApiManager.java). ### Google Site Search (GSS) / Google Custom Search (GSE) [Fess Site Search](https://github.com/codelibs/fess-site-search) provides [scripts](https://fss-generator.codelibs.org/docs/manual) (see below) to help you migrate from GSS/CSE. Using the, you can replace existing GSS/CSE JavaScript codes with: ``` <script> (function() { var fess = document.createElement('script'); fess.type = 'text/javascript'; fess.async = true; fess.src = '//<Fess Server Name>/js/ss/fess-ss.min.js'; fess.charset = 'utf-8'; fess.setAttribute('id', 'fess-ss'); fess.setAttribute('fess-url', '//<Server Name>/json'); var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(fess, s); })(); </script> <fess:search></fess:search> ``` An example of Fess Site Search in use is below:  ### More Reading - [JSON API](https://fess.codelibs.org/12.5/user/json-response.html)
