Rahul Jain created SOLR-8636:
--------------------------------
Summary: Incorrect distance returned for indexed polygon shapes
Key: SOLR-8636
URL: https://issues.apache.org/jira/browse/SOLR-8636
Project: Solr
Issue Type: Bug
Components: spatial
Affects Versions: 5.2.1
Reporter: Rahul Jain
We have a location_rpt field with multivalued=true and we are indexing multiple
shapes of type LINESTRING() in a single spatial field per document. We are
using JTS for spatial and polygon indexing and filtering.
Solr query:
q={!geofilt sfield=geo pt=-27,153 score=distance d=50}&fl=*,score
For above query, we get the results perfectly fine (i.e. documents with at
least one intersecting shape is returned) but the returned distance has
following behavior:
1. When only shapes (LINESTRING(), LINESTRING()) are indexed then the distance
returned is 180 degrees or 20015.115 kms.
2. When only points are indexed then the distance to nearest point is returned.
3. When both points and shapes are indexed, distance to nearest point is
returned.
Using above distance in sorting causes sorting to go haywire.
Does Solr not return the distance it used during document filtering? Is there a
workaround or am I doing something wrong?
