There is that part of it, but it's smaller compared to potential docfreq skew. If I had a document with "ABC" in it, and it only appeared in that document, the docfreq is 1. If I delete that doc, and re-add it, the docfreq may all of a sudden appear to be 2. -Yonik --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
