Thanks - I've got the latter situation, actually. I presume when you wrote your QueryComponent you did the query first execution, modification, and second execution all within the equivalent of the prepare() method? I didn't want to replace QueryComponent itself, since it does a fair bit of stuff, but maybe I can extend it and just override the appropriate method...

I'm not quite clear on what you want ... if you want to "search within previous search results", simply take the original query and turn it into an fq parameter for the next request using the new query as the q parameter. If you want to take some part of the current results to form a new query internally to Solr, it sounds like what you want is a custom QueryComponent. I've done this, for example, to back off a search that had zero results and broaden it automatically. Register a new QueryComponent as "query" and it'll replace the existing one - in solrconfig.xml.
