 >>most of the body text is the same, but I want to group them all under 
one result.

I created this analyzer class to identify content that was "mostly 
similar" but not necessarily identical.

If you feed a small set of documents through it (say your search 
results) it will only emit tokens for sequences of words that it hasn't 
seen before.  Documents that have significantly more tokens going into 
NovelAnalyzer than coming out of NovelAnalyzer are near-duplicates
