That should be:

         my $id = $mit->get_docid();

Is this code taken from an example or documentation?  If so, let me know where
and I'll fix it.

It's not unnamed - "perldoc Search::Xapian::Enquire" says:

       matches <start> <size>
           Takes the start element, and maximum number of elements, and
           returns an array tied to Search::Xapian::MSet::Tied.

Search::Xapian::MSet::Tied doesn't appear to be documented, and I don't
know much about it (Alex wrote it I think) but looking at the code, its FETCH
method just returns a Search::Xapian::MSetIterator object for that offset in
the results.

There was an out-of-date path in xapian.org's omega.conf in CVS which I fixed
by hand after the 1.0.2 release without realising that file was version
controlled, so my fix was overwritten by the 1.0.3 upload.  Now fixed properly
- thanks for reporting this.
