Comment:

 This is the intended behaviour.

 To filter the returned terms, you would ideally subclass
 {{{Xapian::ExpandDecider}}} to specify the criteria for selecting terms to
 return.

 You set the component to Search::Xapian (i.e. the Perl bindings) but refer
 to the PHP example, so I'm not sure which you are using.

 If it's Perl, then you can pass a subroutine or anon sub for the decider,
 e.g.:

 {{{
 #!perl
 $enq->get_eset( 10, $rset, sub { $_[0] !~ /^[A-Z]/ } );
 }}}

 If it's PHP, then I'm afraid that currently such subclassing isn't
 supported in PHP.  The best workaround I can suggest there is to ask for
 more terms than you want and filter the list returned (not ideal as Xapian
 may have to do more work, and you may not get all the terms you want, but
 I think it's the best you can do in PHP currently).
