Chris: Again, many thanks. Of course only *after* you mentioned that Hits is not entirely efficient when looking at many docs did I remember TopDocs and TopFieldDocs had been mentioned. Senior moments and all that....
I completely missed the fact that ConstantScoreQuery doesn't take a query. I'll betchya anything you want it does what I was doing, only more efficiently <G>... Thanks again for all your help, I may actually go away and not bother folks for a while. I'm supposed to have answers to the question "should we use Lucene" by Wednesday, after that the pace will slow a bit as I write real code rather than proof-of-concept - AKA throw-away code, and take considerably more care <G>.
