Benchmarks Enhancements (precision/recall, TREC, Wikipedia)

                 Key: LUCENE-836
             Project: Lucene - Java
          Issue Type: New Feature
          Components: Other
            Reporter: Grant Ingersoll
            Priority: Minor

Would be great if the benchmark contrib had a way of providing precision/recall benchmark
information ala TREC.  I don't know what the copyright issues are for the TREC queries/data
(I think the queries are available, but not sure about the data), so not sure if the is even
feasible, but I could imagine we could at least incorporate support for it for those who have
access to the data.  It has been a long time since I have participated in TREC, so perhaps
someone more familiar w/ the latest can fill in the blanks here.

Another option is to ask for volunteers to create queries and make judgments for the Reuters
data, but that is a bit more complex and probably not necessary.  Even so, an Apache licensed
set of benchmarks may be useful for the community as a whole.  Hmmm.... 

Wikipedia might be another option instead of Reuters to setup as a download for benchmarking,
as it is quite large and I believe the licensing terms are quite amenable.  Having a larger
collection would be good for stressing Lucene more and would give many users a demonstration
of how Lucene handles large collections.

At any rate, this kind of information could be useful for people looking at different indexing
schemes, formats, payloads and different query strategies.
