Johannes, I think your best bet is to create a QParserPlugin that orders the terms of the incoming query. It sounds like you have control over the way that field is indexed, so you could enforce the same ordering when the document comes into Solr. If that's not the case then you'll also want to write an UpdateRequestProcessor:
