Re: Indexing geohash in solrj - Multivalued spatial search
Ok this is a good news ! I will integrate the jar and test the feature :) Only one question regarding the indexing process in solrj. We could index the location data in format : lat,lon in the geohash field? Or we must encode lan lon in the geohash string and then index the encoded string?

The SOLR-2155 patch is a superset (i.e. extends) that field, adding more capability. Are you telling me LWE includes SOLR-2155? Can you point to proof of that please? If it did, then you wouldn't be getting that FieldCache error due to multi-value since SOLR-2155 definitely supports multi-value.

Any hint about indexing and searching on a multivalued geohash field? 2011/9/29 Smiley, David W. dsmi...@mitre.org Hi Alessandro. I can't think of any good reason anyone would use the geohash field type that is a part of Solr today. If you are shocked I would say that, keep in mind the work I've done with geohashes is an extension of what's in Solr, it's not what's in Solr today. Recently I ported SOLR-2155 to Solr 3x, and in a way that does NOT require that you patch Solr. I attached it to the issue just now. ~ David Smiley On Sep 29, 2011, at 9:37 AM, Alessandro Benedetti wrote: Hi all, I have already read the topics in the mailing list that are regarding spatial search, but I haven't found an answer ...

We could index the location data in format : lat,lon in the geohash field? Or we must encode lan lon in the geohash string and then index the encoded string? This is a common point of confusion stemming from the fact that there is another field named LatLonType. If LatLonType was the only field that accepted a latitude,longitude pair then there would be no confusion but the GeoHashField accepts this too. geohash is a name reflecting its internal workings. You don't need to know a thing about geohashes. BTW I think LWE 1.8 is Solr 1.4 based, and I highly doubt my plugin, which should work in Solr 3x, would work in Solr 1.4. Consider upgrading to LWE 2.0 or using plain Solr. ~ David Smiley Author: http://www.packtpub.com/solr-1-4-enterprise-search-server/
