Hi Charlie,
I think I understand what you mean, I had a similar requirement and this
is what we made:
http://www.mysecondhome.co.uk/search.html?view=map
It allows full faceting on all fields the site allows in normal list
search. Some information about my implementation is in my original
thread about this issue
(http://lucene.472066.n3.nabble.com/Geographic-clustering-td502559.html).
Unfortunately in a fit of madness I didn't add my component to version
control and have since lost the source of my little geo-clustering
component (and yes, I'm still hitting myself over the head for that).
If you want more information I'd be happy to help.
Regards,
gwk

Hi,
I'm interested in using geographic clustering of records in a Solr
search index. Specifically, I want to be able to efficiently produce a
map with clustered bubbles that represent the number of documents that
are indexed with points in that general area. I'd like to combine this
with other facets and search constraints, so it can't be entirely
pre-computed.
It looks to me as though LocalSolr (http://www.gissearch.com/localsolr )
is focused on simply constraining search results to a given radius, and
not facets/clustering of the entire index. Searching the archives of
this list, last year, there was some talk about writing custom
geographic clustering components, but I couldn't find code examples.
Does anyone have a working implementation of a geographic clustering
component, or can anyone point to resources that would help in building one?
best,
Charlie
