  43 =head1 NAME
  44
  45 C4::Breeding : module to add biblios to import_records via
  46                the breeding/reservoir API.
  47
  48 =head1 SYNOPSIS
  49
  50     Z3950Search($pars, $template);
  51     ($count, @results) = &BreedingSearch($title,$isbn,$random);
  52
  53 =head1 DESCRIPTION
  54
  55 This module contains routines related to Koha's Z39.50 search into
  56 cataloguing reservoir features.
  57
  58 =head2 BreedingSearch
  59
  60 ($count, @results) = &BreedingSearch($title,$isbn,$random);
  61 C<$title> contains the title,
  62 C<$isbn> contains isbn or issn,
  63 C<$random> contains the random seed from a z3950 search.
  64
  65 C<$count> is the number of items in C<@results>. C<@results> is an
  66 array of references-to-hash; the keys are the items from the C<import_records> and
  67 C<import_biblios> tables of the Koha database.

 123 =head2 Z3950Search
 124
 125 Z3950Search($pars, $template);
 126
 127 Parameters for Z3950 search are all passed via the $pars hash. It may contain isbn, title, author, dewey, subject, lccall, controlnumber, stdid, srchany.
 128 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).
 129 This code is used in acqui/z3950_search and cataloging/z3950_search.
 130 The second parameter $template is a Template object. The routine uses this parameter to store the found values into the template.
