I arrived at this MAP by modifying IndexFiles to use a StopAnalyzer and work in a way that was acceptable for TReC files. The SearchFiles was modified to use a StopAnalyzer and output data in a trec_eval suitable format. Trec_eval reports about 11% at this setting.
I am not competing in TReC I am just doing an evaluation of different search engines. At this point I am not going to add anything to Lucene to get a higher MAP because I am trying to get a feel for its "out of the box" performance.
