Stemming does not work in PRMS2Traversal. Try #prms(us presidents) and #prms(us president). At the same time, #combine(us.names president.names) and #combine(us.names presidents.names) both give the same results on the same index.
The problem is present in all fielded models. Here is my attempt to solve the issue. This breaks the tests, though. I'll work more on it if I will have time.

Here is the new version of patch, which should be applied on top of https://sourceforge.net/p/lemur/bugs/275/#54ea
Tests are working, and specifying --stemmer is not needed now

OK, I'll use it before commits.
Looks like test failures were just the use of stemmed versus unstemmed index parts (at least for the test I looked closely at).
