Jon H created SOLR-7439:
---------------------------
Summary: Large spatial query with high precision yields incorrect
results
Key: SOLR-7439
URL: https://issues.apache.org/jira/browse/SOLR-7439
Project: Solr
Issue Type: Bug
Components: spatial
Affects Versions: 4.10.3
Environment: Windows 7, Oracle JDK 1.8.0_40
Reporter: Jon H
I've noticed that queries with polygons that span more than 180 degrees can be
interpreted as going the opposite way around the earth when the points have
"many" decimal places.
Here are the relevant schema details. Note I am using ccwRect for datelineRule.

<fieldType name="location_rpt" class="solr.SpatialRecursivePrefixTreeFieldType"
spatialContextFactory="com.spatial4j.core.context.jts.JtsSpatialContextFactory"
geo="true" distErrPct="0.1" maxDistErr="0.000009" units="degrees"
datelineRule="ccwRect" normWrapLongitude="true" autoIndex="true"/>

JTS v1.10 jar has been added to the classpath.
A simple test case that shows the problem:
I have 3 documents indexed each with one of the following polygon values set
for the "geo" field.
{quote}
POLYGON ((-0.70312499989791 8.0592296260867, 13.359374998139 8.0592296260867,

When I execute this query, I get only 1 hit:
{quote}
geo:"Intersects(POLYGON((-136.40624998100992
-41.50857729267501,129.02343748203592 -41.50857729267501,129.02343748203583
58.4477327986157,-136.40624998100992 58.4477327986157,-136.40624998100992
-41.50857729267501))) distErrPct=0.0"
{quote}
Now if I run this query where a took off a couple decimal places from each
point, I get 3 hits (this is what I would expect):
{quote}
geo:"Intersects(POLYGON((-136.406249981009 -41.508577292675,129.023437482035
-41.508577292675,129.023437482035 58.44773279861,-136.406249981009
58.44773279861,-136.406249981009 -41.508577292675))) distErrPct=0.0"
{quote}
It looks like the first query is actually doing the opposite of what I intend -
it's being interpreted as the smaller area going the opposite way around the
earth. I may be able alter my queries slightly so that I get the desired
behavior but it seems like these queries should give the same results, correct?
