Xapian discuss - Feb 2013 - Parsing fields with phrases.

I have the following code:

     my $par = 
$qp->parse_query($query,Search::Xapian::FLAG_SPELLING_CORRECTION);
     print LOG "Query $query, par $par\n";
     my $enq = $xDatabase->enquire( $par );

The output from the LOG file is:
Query title:"new dolphin", par Xapian::Query(0 * Snew dolphin)

No results are returned.  If I change the search to title:dolphin it 
finds a number of hits including one who's title is
Introducing the New Dolphin 
<http://localhost/mail/cur/mail.fdcga.com/Inbox/1905.html>

What do I do to make this work the way I want it to?

Thanks,
Jim.

That query description shows a single term: Snew dolphin

This means you set title/S as a boolean prefix, which I doubt is what
you want - titles are better treated as free text fields.

This means you are indexing the title as free text, so if you change:

$qp->add_boolean_prefix("title", "S");

to:

$qp->add_prefix("title", "S");

then it will probably start working as you want.
