[jira] [Comment Edited] (SOLR-8636) Incorrect distance returned for
indexed polygon shapes
[ https://issues.apache.org/jira/browse/SOLR-8636?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17268624#comment-17268624 ]

-------------------------------------------------------
Thank you for your answer [~dsmiley] so maybe the best quick solution is to add another field having a `location` type, for example:
<field name="geo" type="location_rpt" multiValued="true" indexed="true" stored="true"/>
<field name="geo_for_disatance" type="location" indexed="true" required="false" stored="false"/>
The problem that I'm facing wish is the right query to execute to retrieve plogons results around my point. If we have a geo point with lat, lan `(4.0652 44.1518)`
What's the right way to use geodist() in order to search for the results based on *geo* field and display distance on each result based on *geo_for_disatance* field?
```/select?fl=*,_dist_:geodist()&sfield=geo_for_disatance&fq=\{!geofilt sfield=geo pt="4.0652 44.1518" d=6}&pt=4.0652 44.1518&q=*:*``` ? Is it correct !

> 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
> Assignee: David Smiley
> Priority: Major
>
> 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?
