[Xapian-devel] Contributing to Xapian

[Manu Gupta]

Hi

Maybe I can start off with Hanxiao's branch but I can see there are two
repos.

https://github.com/v-hasu/xapian/tree/gsoc2014-evaluation
https://github.com/v-hasu/xapian/tree/gsoc2014

which one should I pick?

I have already successfully built xapian from the git repository (
https://github.com/xapian/xapian)

Since I am new to ML (well I dont know anything about it?), should I read
the paper try to make sense out of it and get back too?

Best Regards
Manu Gupta
