Hi Jian, Thanks for the reply. The problem with that is it completely ignores document length. A book that mentions "frog" 5 times in its 2,000 pages should be less relevant than a book that mentions "frog" 4 times in its 4 pages.
I really want to lower the document length weight instead of removing it completely. Any ideas how to do that?
