Solr 4 spatial queries, jts and polygons
Hi All, I've been trying to get the brand new spatial search functionality working with Solr 4 snapshot apache-solr-4.1-2012-09-24_05-10-26 and also a trunk build from 22 Sep. I have added the jts and jts-io libraries and defined a field as follows: fieldType name=geo class=solr.SpatialRecursivePrefixTreeFieldType spatialContextFactory=com.spatial4j.core.context.jts.JtsSpatialContextFactory units=degrees distErrPct=0.025 maxDistErr=0.09 / [...] dynamicField name=*_geo type=geo indexed=true stored=true multiValued=true / There are no errors during Solr startup, and I can successfully index and search rectangles, but I can't get the polygon search to work. E.g. this search: q=*:*fq=location_geo:%22Intersects%28POLYGON%28%28-10%2030,%20-40%2040,%20-10%20-20,%2040%2020,%200%200,%20-10%2030%29%29%29%22 Results in the following error: Unable to read: POLYGON((-10 30, -40 40, -10 -20, 40 20, 0 0, -10 30)) The call stack implies that JTS is not being used: com.spatial4j.core.exception.InvalidShapeException: Unable to read: POLYGON((-10 30, -40 40, -10 -20, 40 20, 0 0, -10 30)) at com.spatial4j.core.io.ShapeReadWriter.readShape(ShapeReadWriter.java:48) at org.apache.lucene.spatial.query.SpatialArgsParser.parse(SpatialArgsParser.java:89) at org.apache.solr.schema.AbstractSpatialFieldType.getFieldQuery(AbstractSpatialFieldType.java:170) at org.apache.solr.search.SolrQueryParser.getFieldQuery(SolrQueryParser.java:171) [...] As far as I can see, ShapeReadWriter in spatial4j doesn't support polygons, and JTS is needed for that. I've read http://wiki.apache.org/solr/SolrAdaptersForLuceneSpatial4 (which is a bit vague and partly outdated) and some of the JIRA issues too (e.g. SOLR-3304, SOLR-2268, LUCENE-3795), but did not notice what I'm missing. Any pointers or hints on what to do to make this work would be highly appreciated. Thanks! Regards, Ere -- Ere Maijala (Mr.) The National Library of Finland
Spatial queries
Hi All,
I am using the package from JTeam to perform spatial searches on my index. I'd
like to know if it is possible
to build a query that uses multiple clauses. Here is an example:
q={!spatial lat=123 long=456 radius=10} OR {!spatial lat=111 long=222
radius=20}title:java
Basically that would return all documents having the word java in the title
field and that are either
within 10 miles from the first location OR 20 miles from the second.
I've made a few tries but it does not seem to be supported. I'm still wondering
if it would make sense to support this kind of queries.
I could use multiple queries and merge the results myself but then I need some
faceting.
Thanks
