Marcel de Rooy 15088c67d6 Bug 19436: (QA follow-up) Revert change in _handle_one_result
See Bugzilla comment 7. This change does not belong here and is
dubious on its own. Needs further attention on another report.

Signed-off-by: Marcel de Rooy <m.de.rooy@rijksmuseum.nl>

Amended: In consultation with the author the same change is applied to the
corresponding lines in Z3950SearchAuth.

=head1 NAME
C4::Breeding : module to add biblios to import_records via
the breeding/reservoir API.
=head1 SYNOPSIS
Z3950Search($pars, $template);
($count, @results) = &BreedingSearch($title,$isbn,$random);
=head1 DESCRIPTION
This module contains routines related to Koha's Z39.50 search into
cataloguing reservoir features.
=head2 BreedingSearch
($count, @results) = &BreedingSearch($title,$isbn,$random);
C<$title> contains the title,
C<$isbn> contains isbn or issn,
C<$random> contains the random seed from a z3950 search.
C<$count> is the number of items in C<@results>. C<@results> is an
array of references-to-hash; the keys are the items from the C<import_records> and
C<import_biblios> tables of the Koha database.

=head2 Z3950Search
Z3950Search($pars, $template);
Parameters for Z3950 search are all passed via the $pars hash. It may contain isbn, title, author, dewey, subject, lccall, controlnumber, stdid, srchany.
Also it should contain an arrayref id that points to a list of id's of the z3950 targets to be queried (see z3950servers table).
This code is used in acqui/z3950_search and cataloging/z3950_search.
The second parameter $template is a Template object. The routine uses this parameter to store the found values into the template.
