[EP-tech] Searching with multiple compound fields

In EPrints, one can set up compound fields ("creator" is the classic example: it has "given name", "Family name", "honorific", and "id" sub-fields in one EPrint-field. 

I've created a similar field, which I'm now using in a search.

Look at http://devel.edina.ac.uk:1203/45477/
I have an EPrint field called "Target repositories", this is a multipul field, in that I can have more than one "row" 
It's also a compound field, in that each item consists of 11 sub-fields.
All is good, and I can happily read & write data to this setup.... not a problem.
Searching, however, has become an issue - and I wasn't aware of the issue until recently! 

I create a search thus:

  my $ds = $session->get_repository->get_dataset("archive");
  my $search = EPrints::Search->new(
    satisfy_all => 1,
    session     => $session,
    dataset     => $ds,
  );
  my $date_range = '2000-01-01-3000-12-31';
  $search->add_field( $dso->get_field("broker_sent"), $date_range );
  $search->add_field( $dso->get_field("broker_live"), '', 'EX' );
  print $search->render_description->toString if ( $noise > 0 );

This prints a search string that says

  Date sent is between 01 January 2000 and 31 December 3000 inclusive
  <b xmlns="http://www.w3.org/1999/xhtml";>AND</b> Date went live is
  UNSPECIFIED.
Unfortunately it's picking up eprintid 45477 - when obviously (to a human) it shouldn't.
So - how do I restrict a search so that the terms have to be within a single "row" of a multiple compound field?
