pre-loaded function-query?

Hello Solr experts, I'm writing a "query expansion" QueryComponent which takes web-app parameters (e.g. profile information) and turns them into a solr query. Thus far I've used lucene TermQuery-ies with success. Now, I would like to use something a bit more elaborate. Either I write it with qui
