Xapian discuss - Nov 2004 - Adding an rset to a query

Hi,

I'm using xapian here with the perl api - can someone show me how I'm 
meant to refine a query using an rset? Something like:

my $rset = new Search::Xapian::QueryParser();
$rset->addDocument(120);
$rset->addDocument(163);
$rset->addDocument(023);

my $enq = $db->enquire( $qp->parse_string ($terms), $rset);

Cheers,
Ben

                                 ^^^^^^^^^^^ RSet, not QueryParser!

         ^^^^^^^^^^^ add_document, not addDocument

And perl will treat 023 is octal, which I doubt was intended.  But this
probably isn't real code anyway...

                                                    ^^^^^^^ don't pass here

And then you can get an ESet like this:

my $eset = $enq->get_eset(20, $rset);

And read terms from the ESet like this:

for (my $i = $eset->begin(); $i != $eset->end(); ++$i) {
    print $i->get_weight(), "\t", $i->get_termname(),
"\n";
}

Although I've not tested the above as I don't currently have the perl
bindings built.
