Hi, Sorry for the long hiatus. I was caught with some other deadlines. Could some one tell me some specific expectations from Letor for GSOC 2015? I am currently trying out some learning algorithm implementations but need some help with it. Can Parth, James and others related to LETOR please tell me the IRC availability for the next few days.

It will result in more features, and hopefully an easier API to work with by the end of it, but unfortunately I can't give a concrete timescale to get things done by. > > J > > -- > James Aylett, occasional trouble-maker > xapian.org >

The best thing to do is ask a question in the channel, and wait for a response. Cheers, Olly
Hi, Can someone tell me what was Gaurav Arora's exact contribution in the Clustering Search Results part during GSoC 2014? I guess that will be more helpful in understanding his code.
