I'm trying to write some unit tests for the MoreLikeThisHandler which test the functionality. I've added documents, committed them, but can't get the query to return a single document from which mlt would get terms. It's as if the documents aren't making it to the index or I'm query them incorrectly. I'm stuck at this point. Can someone take a look at the attached unit tests and let me know if I'm missing something.
Thanks...Tom
