Ahh I realise I am to blame for some of the confusion. I haven't
stated clearly, I do think adding Solr would be beneficial, and I
would be happy to accept patches that do that, as long as they do it
in a way that provides a search engine abstraction layer. I'd hate to
see us lock ourselves hard to another search engine and have to redo
it all again when we find a better one.
If we are working towards DB abstraction, lets do Search engine abstraction too.
