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
