With Geo Search you can control the sorting based on geographical distance from a given start position/geographical location.
FAST ESP supports geographical coordinates associated with documents, and lets you sort and filter results based on radius or a rectangular geographical area. Using the filter option you can use regular sorting or ranking. Sorting based on distance can not be combined with regular ranking.
To search with Geo sort/filter :
1. GEO search must be enabled in the back-end.
2. GEO data must be fed into FAST ESP.
To Enable Geo in Fast SFE :
1. Open $FASTSEARCH/adminserver/webapps/sfe/WEB-
INF/classes/com/fastsearch/espimpl/sfeapi/searchservice/SearchServiceImpl.properties
2. Add com.fastsearch.espimpl.sfeapi.searchservice.search.geo.LatLonGeoSearchImpl to custom_search_inputs=
3. Add com.fastsearch.espimpl.sfeapi.searchservice.result.geo.GeoGraphImpl to custom_result_aspects=
4. Restart the ESP using nctrl restart command.
Now you can see the Geo features in SFE under the Advanced search Tab.
