Xapian discuss - Nov 2005 - sort by multiple values

Apologies if this question is answered in the docs and/or in the list archive. I
checked both.

I'm wondering if there is currently a feature to sort by multiple document 
values. For example, sort first by timestamp, then by URL. I see 
set_sort_by_value() works for a single value.

Thanks.

There isn't.  The plan is to allow the user to specify a custom search
function by subclassing a functor (like how MatchDecider works).

There are some relevant thoughts in this (closed) bug report:

A question about stemmer.

When I stem query I use the following code:
pqp=new QueryParser();
           Stem stem(sLang);
           pqp->set_stemmer(stem);
           pqp->set_database(*_pdatabase);
           pqp->set_default_op(Query::OP_AND);
           Query p=pqp->parse_query(_sXapian);

But it does not seem to stem the words.

Hello ,
when I try to stem a query using the following code the phrase does not
seem to be stemmed. I use Xapian version 0.9.2.

           pqp=new QueryParser();
           Stem stem(sLang); //Language tried is Norwegian
           pqp->set_stemmer(stem);
           pqp->set_database(*_pdatabase);
           pqp->set_default_op(Query::OP_AND);
           //Set the enquire
           Query p=pqp->parse_query(_sXapian);


When I try to stem using the stem class and stem_word is works.

Does not Query Parser work properly for stemming ?
