[Xapian-devel] Pull request for optimized InL2 and IfB2 weighting schemes

[Aarsh Shah]

Hello,

I have sent a pull request for an optimized upper bound and weighting
calculations of the ifb2 and inl2 weighting schemes. I rearranged and
simplified the formula to identify and cancel out the common factors in
order to achieve both the goals. I also ran the automated tests on the
patch and all of them work well on all back ends.

I am now working on optimization of DPH. It is proving to be a bit of
challange because of the complexity of the formula involved but I think I
am making progress towards it and should be done by tomorrow night.
