> URL: https://issues.apache.org/jira/browse/SOLR-4879
> Project: Solr

> Environment: Linux, Solr 4.0.0, Solr 4.3.0

>
> When trying to index a field of the type solr.SpatialRecursivePrefixTreeFieldType the indexing will fail if two vertexes are more than 180 longitudal degress apart.
> For instance this polygon will fail:
> POLYGON((-161 49, 0 49, 20 49, 20 89.1, 0 89.1, -161 89.2, -161 49))
> but this will not.
> POLYGON((-160 49, 0 49, 20 49, 20 89.1, 0 89.1, -160 89.2, -160 49))
> This contradicts the documentation found here: http://wiki.apache.org/solr/SolrAdaptersForLuceneSpatial4
> The documentation states that each vertex must be less than 180 longitudal degrees apart from the previous vertex.
> Relevant parts from the schema.xml file:
> <!-- Field type for storing WTK based polygons -->
> <fieldType name="location_rpt" class="solr.SpatialRecursivePrefixTreeFieldType"
> spatialContextFactory="com.spatial4j.core.context.jts.JtsSpatialContextFactory"
> distErrPct="0.025"
> maxDistErr="0.000009"
> units="degrees"
> />
> <field name="geographic_extent" type="location_rpt" index="true" stored="true" />
