Xapian discuss - Nov 2014 - finer-granular document weight

thanks J; I assume get_weight() returns non-negative numbers where the upper
bound changes per query (it is not bound by a particular number like 1 or 1000),
correct?

get_weight(), on the MSetIterator, is probably what you want. get_percent()
isn?t particularly useful in most cases; weight is a floating point number
(double).

That will depend on your weighting scheme, but usually that will be correct. For
information on the default weighting scheme see
