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

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