GEODIST SOLR HOW TO

The default blank value does not support polygons. There are two built-in aliases for known implementations: Geo3D and JTS. spatialContextFactory This is a Java class name to an internal extension point governing support for shape definitions & parsing. Solr requires a field type to parallel these in order to use them. But be aware that the Lucene spatial module includes some other so-called 'spatial strategies' other than RPT, notably TermQueryPT*, BBox, PointVector*, and SerializedDV. class This should be solr.SpatialRecursivePrefixTreeFieldType. For example, to find all documents within five kilometers of a given lat/lon point, you could enter: Another way of looking at it is that it creates a circular shape filter. The geofilt filter allows you to retrieve results based on the geospatial distance (AKA the 'great circle distance') from a given point. If you only want the query to score (with the above score local parameter), not filter, then set this local parameter to false.

area2D: cartesian coordinates based area of the overlapping shapes expressed in terms of the distanceUnits configured for this fieldįilter (Advanced option not supported by LatLonType (deprecated) or PointType).

area: haversine based area of the overlapping shapes expressed in terms of the distanceUnits configured for this field.

overlapRatio: The relative overlap between the indexed shape & query shape.

When used with BBoxField, additional options are supported: And with RPT, it’s only recommended for multi-valued point data, as the implementation doesn’t scale very well and for single-valued fields, you should instead use a separate non-RPT field purely for distance sorting. Here’s how LatLonPointSpatialField (LLPSF) should usually be configured in the schema:ĭon’t use this for indexed non-point shapes (e.g., polygons). Some esoteric details that are not in this guide can be found in the Spatial Search section of the Solr Wiki.

It can’t do sorting/boosting.īBoxField is for indexing bounding boxes, querying by a box, specifying a search predicate (Intersects,Within,Contains,Disjoint,Equals), and a relevancy sort/boost like overlapRatio or simply the area. RptWithGeometrySpatialField is for indexing and searching non-point data though it can do points too. RPT offers some more features for more advanced/custom use cases and options like polygons and heatmaps. It replaces LatLonType which still exists for backwards compatibility. LatLonPointSpatialField is the ideal field type for the most common use-cases for lat-lon point data. SpatialRecursivePrefixTreeFieldType (RPT for short), including RptWithGeometrySpatialField, a derivative.LatLonType (now deprecated) and its non-geodetic twin PointType.Solr supports location data for use in spatial/geospatial searches.
