What kind of documents do you have?  Are they very similar to the TREC docs 
(i.e. news articles)?  There can be a fairly wide difference in performance 
between real docs and TREC docs, especially given real queries.  Doing well at 
TREC does not necessarily equate to doing well in your own system.  You might 
be better off just doing something like taking the top 50 queries from your 
logs plus some random ones from the tail and judging the top 10.   See
