Hi Rainer,
I see two issues. One is that you call makePoint with latitude (Y) then
longitude (X). Spatial4j is X

bug, perhaps start with the SpatialExample.java in a working state and
iteratively modify it to work how you want it to, testing each time that

Hi,
If you would index additional grid ids for the bins, you could facet on them.
To me, Elasticsearch's Aggregation Module may also be a good fit.

I need a way to perform a spatial aggregation query against a potentially large
document store in order to display summary clusters on a map. The query would
slice the current map extents (e.g. -180,-90,180,90) into a number of X and Y

Does Lucene have a primary and a secondary filter (like MS SQL or PostGIS)

Hi Guillermo,
I think you will find that Lucene Spatial is going under a significant rewrite
in the coming weeks, so I'm hesitant to recommend you upgrading to it at this
point in time. That being said, the concepts behind Lucene Spatial and
LocalLucene aren't all that different, so
I had seen those, but they don't quite help on our problem of migrating from
LocalLucene 2.0 to Lucene Spatial. We don't use Solr.
Thanks though.
Anybody using Lucene Spatial, without Solr, wanting to share some code for
a basic geographical search?
