[Xapian-devel] GSOC 2011 : Weighting Schemes and Matcher Optimisations

[Santiago Pina Ros]

Thanks for the documents. I have read it and understand a bit  more Xapian´s
engine.

Now I feel ready to write my proposal. First of all I have to decide in
which optimisations should I focus my efforts.
How many optimisations do you expect from me to do? Wich ones do you think I
could tackle?
I think that "Boolean OR could be optimised
further<http://trac.xapian.org/ticket/215>"
could be a great optimisation.

Cheers,
    Santiago
