For my particular case, word repetition shouldn't be relevant in determining
the rank of a document. If I strip() the vector, I loose what relevance
proximity and weight add to the rank. It seems impossible, yet I ask anyway: Is
it possible to eliminate the second (third, fourth, fifth, etc.) occurrence of
any given word when its presence in the document is being scored, yet kept in
the equation for modifications to the score when proximity is being considered?
