Not directly related to geo clustering, but http://issues.apache.org/jira/browse/SOLR-769
is all about a pluggable interface to clustering implementations.
It currently has Carrot2 implemented, but the APIs are marked as
experimental. I would definitely be interested in hearing your
experience with implementing your clustering algorithm in it.

Hi,
I'm working on a search-on-map interface for our website. I've
created a little proof of concept which uses the MarkerClusterer (http://code.google.com/p/gmaps-utility-library-dev/
) which clusters the markers nicely. But because sending tens of
thousands of markers over Ajax is not quite as fast as I would like
it to be, I'd prefer to do the clustering on the server side. I've
considered a few options like storing the morton-order and throwing
away precision to cluster, assigning all locations to a grid
position. Or simply cluster based on country/region/city depending
on zoom level by adding latitude on longitude fields for each zoom
level (so that for smaller countries you have to be zoomed in
further to get the next level of clustering).
I was wondering if anybody else has worked on something similar and
if so what their solutions are.

gwk
