43 =head1 NAME
45 C4::Breeding : module to add biblios to import_records via
46 the breeding/reservoir API.
48 =head1 SYNOPSIS
50 Z3950Search($pars, $template);
51 ($count, @results) = &BreedingSearch($title,$isbn);
53 =head1 DESCRIPTION
55 This module contains routines related to Koha's Z39.50 search into
56 cataloguing reservoir features.
58 =head2 BreedingSearch
60 ($count, @results) = &BreedingSearch($title,$isbn);
61 C<$title> contains the title,
62 C<$isbn> contains isbn or issn,
64 C<$count> is the number of items in C<@results>. C<@results> is an
65 array of references-to-hash; the keys are the items from the C<import_records> and
66 C<import_biblios> tables of the Koha database.

119 Z3950Search($pars, $template);
121 Parameters for Z3950 search are all passed via the $pars hash. It may contain isbn, title, author, dewey, subject, lccall, controlnumber, stdid, srchany.
122 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).
123 This code is used in acqui/z3950_search and cataloging/z3950_search.
124 The second parameter $template is a Template object. The routine uses this parameter to store the found values into the template.
