[Xapian-devel] How to add an custom weight to the relevancy value and sort it.

[Parth Gupta]

Hi Vishnu,

You need to use quest.cc like program and perform your operations on the
mset.

See lines 165-172 of
http://trac.xapian.org/browser/branches/gsoc2011-parth/xapian-core/examples/quest.cc

And you can add your weights to the i.get_weight()->store in a map with
docid and sort it. To sort it you can use something like lines 235-244 of
http://trac.xapian.org/browser/branches/gsoc2011-parth/xapian-letor/examples/questletor.ccwhich
basically calculates new weights for the documents, add it in a
sorted map and reprint it.

Parth.
