Indexing geohash in solrj - Multivalued spatial search
Hi all,
I have already read the topics in the mailing list that are regarding
spatial search, but I haven't found an answer ...
I have to index a multivalued field of type : "geohash" via solrj.
Now I build a string with the lat and lon comma separated ( like
54.569468,67.58494 ) and index it in the geohash field.
The indexing process seems to work , but when I try a spatial search, Solr
returns me an exception with fieldcache on multivalued field.
I'm using Lucid Work enterprise 1.8 , and , as I know , it should be
integrated with this patch (
https://issues.apache.org/jira/browse/SOLR-2155?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12994256#comment-12994256
).
Am I indexing wrong? Am I missing something?
The type of my spatial field is geohash ...
Cheers

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.

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?
Thank you

Solr 3x, trunk, and I suspect Lucid Works Enterprise 2.0 (doubtful 1.8)) supports this:
<fieldtype name="geohash" class="solr.GeoHashField"/>
That is not "the patch" -- SOLR-2155, that is the standard built-in geo support in Solr 3x.
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.
You may have luck putting my SOLR-2155 compiled plugin jar in LWE 1.8 according to the instructions I provide; I don't know.

Sorry David, probably I misunderstood your reply, what do you mean?
I'm using Lucid Work Enterprise 1.8, and, as I know , it includes geohashes
patch.
I have to index a multivalued location field and I have to make location
queries on it!
So I figured to use the geohash type ...
Any hint about indexing and searching on a multivalued geohash field?

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.
