Summary: Multipolygon query problem with datelineRule=ccwRect
Key: SOLR-6534
URL: https://issues.apache.org/jira/browse/SOLR-6534
Project: Solr
Issue Type: Bug
Components: spatial
Affects Versions: 4.9
Environment: Windows 7, Oracle JDK 1.7.0_45
Reporter: Jon Hines
We are currently upgrading from Solr 4.1 to 4.9 and have observed some odd
behavior with multipolygon queries now. It is difficult to describe what is
happening so I took a screenshot with the documents and query area plotted on a
map. You can see it here: [http://imgur.com/iBpYLMh] The blue areas represent
the multipolygon and the purple areas represent the document footprints.
The query being used is as follows:
{quote}
geo:"Intersects(MULTIPOLYGON(((-3 2,4 2,4 8,-3 8,-3 2)),((-3 -11,4 -11,4 -4,-3
-4,-3 -11))))
{quote}
This query returns all results when it should be returning only 8. If I run two
separate queries with each individual polygon, I get 4 hits each as expected.
I've narrowed this down to a problem with using 'datelineRule=ccwRect'. If I
remove this setting, the query returns with the expected results.
Unfortunately, this setting is required for our software though, since handling
large polygon queries (spanning >180 degrees) are a requirement.
Here are the relevant schema details:
{quote}
<field name="geo" type="location_rpt" indexed="true" stored="false"/>
<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"/>
