nice! i think lucene 4.0.0 is worth the switch for downstream tasks/retrieval, but currently we don't use lucene for much. given that it shouldn't be too much refactoring (james can comment -- he recently did a conversion from 3.6.1 to 4.0.0), i vote we go to 4.0.0.

What version of Lucene are we upgrading to? 3.6.1? That's the latest from the 3.X series. The current version is 4.0.0, but that probably involves some code updates as well. Keeping up with Lucene releases and API changes is a full time job. ;-) Steve
