Well done, Grant. Very informative.
Question on Term Vectors: with their inclusion in an index, have you noticed
any degradation in performance, either from a search effiiciency or
maintenance point-of-view? Given the power of term vectors, if the perf
impact is negligible, I'm curious to the re
Hi Erik
Thanks for your solution. I want to do exactly what you have mentioned in

We use boosts that are calculated based on the frequencies and the
standard alpha, beta, gamma multipliers from Rochio. Non-relevant terms
decrement the frequency. If a term is <= 0, we remove the term (someone
