[development] ApacheSolr for Content Profile searches

[Don]

Does anyone have experience using ApacheSolr Search for searching 
registered membership lists? I would think the profile would be just 
another node that could be added, with fields like state and city as 
facets. It would be nice to have some containment,  like after state, 
then a list of cities. Fields searched depending on private or public, 
though I could probably put that into the facet theming.

Thanks.
