Xapian discuss - Dec 2006 - Changing weights per field

I'm not entirely sure if the following is possible with xapian (didn't
see
much in the way of the documentation that says it is).

I have four fields which reference a PK in our DB that I'd like to index (in
most weighted to least weighed order): full name, e-mail, title and
location. I see I how I can use add_document() to add a concatenated string
of the 4 fields, but how would I give weights to them at search time? I'm
using the python bindings.

Cheers,

If you build the query yourself, you can set the wqf (within query
frequency) of each term in the query - it's an optional parameter to
the Query constructor which takes a term name.

Or you can do the work at index time by specifying a larger wdf
increment for terms from certain fields when calling
Document::add_posting() (or Document::add_term()).
