Xapian discuss - Apr 2010 - Question from a new user of xapian: query term weight

Hi all,

I've been a Lucene user for the past year, but lately, with most of my
project moving to Python, I really love Xapian's clean python binding.
 I can't seem to see how to boost a query term using Xapian's query
syntax.  In Lucene, there is "hello^4 world^.2" to boost
"hello" and
suppress "world".  However, digging through Xapian's
documentation, I
only see that Xapian supports boosting of document terms (restricted
to integers), but not query terms.

Any help would be deeply appreciated.

You can also boost at query time by any non-negative factor:

There's no syntax for this in the QueryParser currently though.
