Gee, I was about to post. I figured my issue is that of computing the unique terms per document. One approach to compute that value is running the analyzer on the document before before calling addDocument, and count the number of tokens. Then I can invoke addDocument with the value of the field computed.
The only issue is that I'm here making the assumption that if I use the same Analyzer addDocument used in addDocument then that will always equal the number of terms indexed for that document. Is that a right assumption? Any alternative where I don't need to make this assumption?
