self intersecting polygon errors
http://lucene.472066.n3.nabble.com/file/n4024423/5-12-2012_9-26-09_PM.jpg Hi, trying to play with polygon searches and have noticed this issue. It seems when you cross a line you invalidate the polygon (Sorry I have no idea about the technical term) and solr cannot handle it. As far as my google fu goes, there is no fix, its not specific to solr, its to do with geometry moreso. Anyone have a work around? Could this be fixed or should I just try and control this at the customer front end script to check if the shape is valid. Using Solr4 and I think current version of JTS (downloaded/installed in mid November).

how to do a range search not on ordered data (text type)
Hi, Im building a solr install which has a blurb of data in a field description. In that field there are sentences such as This property has a block size of 770sqm. or 1200sqm block blah blah blah. Its a text field obviously. How can I construct a search as follows. Someone wants to search for properties with the block size over 900sqm. with a block size under 1200sqm. with a block size of between 550 and 1500sqm. Its essentially a text string but can you range values in text somehow? Thanks in advance. -- View this message in context: http://lucene.472066.n3.nabble.com/how-to-do-a-range-search-not-on-ordered-data-text-type-tp4023761.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: solr4 MULTIPOLYGON search syntax
Thanks to both of you. I got it working as follows after your helpful posts. I get this polygon search working. fq=geo:Intersects(POLYGON((149.4023 -34.6072, 149.4023 -34.8690, 149.9022 -34.8690, 149.9022 -34.6072, 149.4023 -34.6072))) AND I can get this search working (as in results returned) fq=geo:Intersects(POLYGON((151.506958 -33.458943, 150.551147 -33.60547, 151.00708 -34.257216, 151.627808 -33.861293, 151.506958 -33.458943))) But no matter what MULTIPOLYGON I try with various Parentheses combinations and im still not getting results, I will get results from either only 1 of the polygons in the multipolygon search, or the error unable to read . fq=geo:Intersects(MULTIPOLYGON(((149.4023 -34.6072, 149.4023 -34.8690, 149.9022 -34.8690, 149.9022 -34.6072, 149.4023 -34.6072))), ((151.506958 -33.458943, 150.551147 -33.60547, 151.00708 -34.257216, 151.627808 -33.861293, 151.506958 -33.458943))) Returns only the results from the first polygon. fq=geo:Intersects(MULTIPOLYGON(((149.4023 -34.6072, 149.4023 -34.8690, 149.9022 -34.8690, 149.9022 -34.6072, 149.4023 -34.6072)), ((151.506958 -33.458943, 150.551147 -33.60547, 151.00708 -34.257216, 151.627808 -33.861293, 151.506958 -33.458943))) Gives error ERROR 500 error reading WKT Finally this fq=geo:Intersects(MULTIPOLYGON(((149.4023 -34.6072, 149.4023 -34.8690, 149.9022 -34.8690, 149.9022 -34.6072, 149.4023 -34.6072)), ((151.506958 -33.458943, 150.551147 -33.60547, 151.00708 -34.257216, 151.627808 -33.861293, 151.506958 -33.458943 Worked :) -- View this message in context: http://lucene.472066.n3.nabble.com/solr4-MULTIPOLYGON-search-syntax-tp4021199p4021435.html Sent from the Solr - User mailing list archive at Nabble.com.
solr4 MULTIPOLYGON search syntax
Does anybody have any info on how to property construct a multipolygon search? Im very interested in Polygon (search all documents within a shape) Multipolygon (search all documents within 2+ shapes) Multipolygon (search all documents with 2+ shapes but not within an area within a shape - if you can image a donut where you dont search within the hole in the center) Im trying to search 2 shapes but get errors at the moment. Polygon searches work just fine so I have everything installed correctly, but 2 shapes in the one search as per below is not working. I cant find anything on the net to try and debug Multipolygons. My multipolygon query looks like this. fq=geo:Intersects(MULTIPOLYGON ((149.4023 -34.6072, 149.4023 -34.8690, 149.9022 -34.8690, 149.9022 -34.6072, 149.4023 -34.6072)), ((151.506958 -33.458943, 150.551147 -33.60547, 151.00708 -34.257216, 151.627808 -33.861293, 151.506958 -33.458943))) And I get this error. ERROR 500 error reading WKT But a polygon search works fine. fq=geo:Intersects(POLYGON((149.4023 -34.6072, 149.4023 -34.8690, 149.9022 -34.8690, 149.9022 -34.6072, 149.4023 -34.6072))) -- View this message in context: http://lucene.472066.n3.nabble.com/solr4-MULTIPOLYGON-search-syntax-tp4021199.html Sent from the Solr - User mailing list archive at Nabble.com.
