[Xapian-devel] Contributing to Xapian

[Hanxiao Sun]

Hi~ Manu

I was glad to see you were interested in Xapian, especially the learning to
rank project. There are two branch in my repo. The one named gsoc2014
is followed the thought of Parth's work in which we not assign the test set
for each ranking and in another one gsoc2014-evaluation we assign the
training set and test set explicitly so that we can get the evaluation
score of each ranking algorithm based on its performance on the test
set. In a nutshell, my suggestion is to choose the gsoc2014-evaluation.

As to your compile errors, I have tested the branch just now and it works
well on my side. Maybe you should read the HACKING under the xapian-core.
It can help you to know how to hacking on Xapian more clearer. Take it
easy. It also takes me many time before I can contribute something.
