Re: GSoC 2016 Letor dataset discussion

I used a subset of INEX 2009 with around 2M documents (some details here:
https://trac.xapian.org/wiki/GSoC2011/LTR/Notes#IREvaluationofLetorrankingscheme)
and it worked fine. If you have access to it, should work for most of our
purposes.

As the INEX documents have rich xml meta-data, letor can benefit in terms
of fields (title, body etc.)

For unit-testing, as James mentions, go with automated tests in a
controlled environment. Use INEX data-set for explicit evaluation and see
if everything works without breaking at large scale.

Cheers
