--------------------------------------------------------------
Fantastic!
it does get confusing with the different versions, patches, and issues.
and in the light shed here, I can see that i also need to add the plugin, and
then the example query should work too.
notes on the wiki, bottom of http://wiki.apache.org/solr/SpatialSearch
and in the filter section of: http://wiki.apache.org/solr/SpatialSearchDev may
be helpful.
however, the addendum will be the most help by making the above information
explicit.
For example: for solr 3.4 to add the geohash filter plugin is it
<queryParser name="geo" class="solr.SpatialGeoHashFilterQParser$Plugin" />
or
<queryParser name="geo" class="solr.SpatialGeohashFilterQParser$Plugin" />
or something else... geohashfilt, since class is not found in either case.
another question on the query, is geohashfilt used same as the geofilt?
thank you.

> There currently isn't a solution in Solr for doing geospatial filtering on
> documents that have a variable number of points. This scenario occurs when
> there is location extraction (i.e. via a "gazateer") occurring on free text.
> None, one, or many geospatial locations might be extracted from any given
> document and users want to limit their search results to those occurring in a
> user-specified area.
> I've implemented this by furthering the GeoHash based work in Lucene/Solr
> with a geohash prefix based filter. A geohash refers to a lat-lon box on the
> earth. Each successive character added further subdivides the box into a 4x8
> (or 8x4 depending on the even/odd length of the geohash) grid. The first
> step in this scheme is figuring out which geohash grid squares cover the
> user's search query. I've added various extra methods to GeoHashUtils (and
> added tests) to assist in this purpose. The next step is an actual Lucene
> Filter, GeoHashPrefixFilter, that uses these geohash prefixes in
> TermsEnum.seek() to skip to relevant grid squares in the index. Once a
> matching geohash grid is found, the points therein are compared against the
> user's query to see if it matches. I created an abstraction GeoShape
> extended by subclasses named PointDistance... and CartesianBox.... to support
> different queried shapes so that the filter need not care about these details.
> This work was presented at LuceneRevolution in Boston on October 8th.
