Class SpatialFilterQParserPlugin
java.lang.Object
org.apache.solr.search.QParserPlugin
org.apache.solr.search.SpatialFilterQParserPlugin
- All Implemented Interfaces:
- NamedListInitializedPlugin
- Direct Known Subclasses:
- SpatialBoxQParserPlugin
public class SpatialFilterQParserPlugin
- extends QParserPlugin
Creates a spatial Filter based on the type of spatial point used.
The field must implement SpatialQueryable
All units are in Kilometers
Syntax:
{!geofilt sfield=<location_field> pt=<lat,lon> d=<distance>}
Parameters:
- sfield - The field to filter on. Required.
- pt - The point to use as a reference. Must match the dimension of the field. Required.
- d - The distance in km. Required.
The distance measure used currently depends on the FieldType. LatLonType defaults to using haversine, PointType defaults to Euclidean (2-norm).
Examples:
fq={!geofilt sfield=store pt=10.312,-20.556 d=3.5}
fq={!geofilt sfield=store}&pt=10.312,-20&d=3.5
fq={!geofilt}&sfield=store&pt=10.312,-20&d=3.5
Note: The geofilt for LatLonType is capable of also producing scores equal to the computed distance from the point
to the field, making it useful as a component of the main query or a boosting query.
