Testing for scalar intervals.

Hi.

I'm new to Xapian.

I have "documents" that contains some scalar
values.. and I'd like to
search them .. this is for example the
"documentsize":

I've read this:
http://lists.tartarus.org/pipermail/x
apian-discuss/2005-January/000681.html
That suggests:

    my $query =
Search::Xapian::Query->new("foo");
    my $filter = Search::Xapian::Query->new(OP_OR, map
{"XAGE$_"} (20..30));
    $filter = Search::Xapian::Query->new(OP_AND, $filter,
"XSEXm");
    my $enquire = $db->enquire(OP_FILTER, $query,
$filter);

But when search large intervals this filterexpression get
large and the
performance suffers. .. And open intervals are even
unsolved:

"give me documents matching "soap opera" that
is larger than 1500 (bytes)"

Indexing "DOCSIZE1500" into the engine.

Is there a way to query the index for these scalar values ..
or is
post-processing of the document-set the only option?

(Using the Perl-API for Xapian)
