Xapian discuss - Jul 2007 - QueryParser problems? (from Perl?)

I'm currently on 1.0.2 and the matching Search::Xapian perl modules.

I input the following and the queryparser somehow doesn't seem to be
detecting the operators?
Am I missing something?

Thanks,
Eric



INPUT: a word OR two NEAR "a phrase" NOT (too difficult) +eh

PARSED: Xapian::Query((Za:(pos=1) AND Zword:(pos=2) AND or:(pos=3) AND
Ztwo:(pos=4) AND near:(pos=5) AND Za:(pos=6) AND phrase:(pos=7) AND
not:(pos=8) AND Ztoo:(pos=9) AND Zdifficult:(pos=10) AND
Zeh:(pos=11)))


#!/usr/bin/perl
use Search::Xapian qw(:standard);

my $dbpath = '/path/to/db';
my $query = 'a word OR two NEAR "a phrase" NOT (too difficult)
+eh';
print "INPUT: $query\n\n";

my $db = Search::Xapian::Database->new($dbpath) || die "Could not
open";

my $stemmer = Search::Xapian::Stem->new('english');

my $qp = new Search::Xapian::QueryParser( $db );
$qp->set_stemmer($stemmer);
$qp->set_default_op(OP_AND);
$qp->set_stemming_strategy(STEM_SOME);

my $q = $qp->parse_query($query);
print "PARSED: " . $q->get_description . "\n";

Hello,

Should I be putting this in a bug report?
Is this something that others can replicate?

Thanks,
Eric

This example (from the pod documentation) is bogus.  You can't currently
do NEAR on a phrase.  I'll change the example to one which actually
works.

It's bad to hardwire numeric values for manifest constants into your
scripts as they are an implementation detail and could change in the
future (it's bad that the pod documentation even mentions them - I've
fixed that in SVN).  To specify multiple flags, combine them with
bitwise OR (|) - the documentation now mentions that too.
