Hi, I’m using Solr 4.10.2 with an up to date version of JTS and spatial4j. As field type in my schema.xml i’m using “location_rpt” like the description in the documentation. ( http://wiki.apache.org/solr/SolrAdaptersForLuceneSpatial4#How_to_Use)
location_rpt field type setup: <fieldType name="location_rpt" class="solr.SpatialRecursivePrefixTreeFieldType" spatialContextFactory="com.spatial4j.core.context.jts.JtsSpatialContextFactory" distErrPct="0.025" maxDistErr="0.001" units="degrees" /> <field name="latlon_rpt" type="location_rpt" indexed="true" stored="true" multiValued="true" /> My filter query like this : latlon_rpt:"INTERSECTS (POLYGON((16.243972778320312 48.27016879304729, 16.411170959472656 48.268340583150504, 16.44275665283203 48.19058119922813, 16.32396697998047 48.15921534239267,16.243972778320312 48.27016879304729))) Everything works fine. My problem is when i am trying to use a more complex polygon (self-intersecting) Solr only shows an Error like this: "Couldn't parse shape 'POLYGON((-87.525029 41.676998,-87.508635 41.680781,-87.494559 41.681037,-87.485719 41.680332,-87.475333 41.677447,-87.465205 41.675011,-87.443232 41.667574,-87.434992 41.658084,-87.443876 41.653338,-87.435615 41.646604,-87.43216 41.641409,-87.432332 41.630857,-87.432374 41.621907,-87.432418 41.611289,-87.433083 41.606523,-87.432718 41.600475,-87.432846 41.58709,-87.433018 41.577716,-87.432675 41.565902,-87.424092 41.560892,-87.423147 41.548814,-87.425594 41.540271,-87.439713 41.530443,-87.471643 41.520933,-87.493787 41.517463,-87.525721 41.516847,-87.52572 41.570552,-87.536797 41.574096,-87.545295 41.577723,-87.549801 41.577852,-87.568684 41.57737,-87.568727 41.587835,-87.56907 41.639941,-87.524953 41.625187,-87.525471 41.648549,-87.539761 41.6481,-87.539751 41.643562,-87.543345 41.646272,-87.548001 41.650056,-87.5362 41.650089,-87.533582 41.650056,-87.533625 41.648292,-87.525492 41.648549,-87.525029 41.676998))' because: com.spatial4j.core.exception.InvalidShapeException: Self-intersection at or near point (-87.52917652682729, 41.648432570220756, NaN)","code":400} Are there any workarounds to get self-intersecting polygon query to work?
