That's a good find!  They use Lucene too!

I don't see any legal issues to us writing code that parses these files. 
  To be safest, I don't think we should republish the files, or even any 
of the queries, but I don't think we should need to.  Folks can download 
them to their own machines and use them for testing there.

It doesn't look as though there's click data, so we can't use this for 
relevance experiments without manually creating judgments.  But for 
performance benchmarking it could be useful.
