147 * @servers is optional. Defaults to biblioserver as found in koha-conf.xml
148 * $offset - If present, represents the number of records at the beggining to omit. Defaults to 0
149 * $max_results - if present, determines the maximum number of records to fetch. undef is All. defaults to undef.
154 * $error is a empty unless an error is detected
155 * \@results is an array of records.
156 * $total_hits is the number of hits that would have been returned with no limit

2105 This function returns an array reference that contains the search parameters to be
2106 passed to the Z39.50 search script (z3950_search.pl). The array elements
2107 are hash refs whose keys are name, value and encvalue, and whose values are the
2108 name of a search parameter, the value of that search parameter and the URL encoded
2109 value of that parameter.
2111 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.
2113 The search parameter values are obtained from the bibliographic record whose
2114 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().
2116 If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g.
2117 a general purpose search argument. In this case, the returned array contains only
2118 entry: the key is 'title' and the value and encvalue are derived from $matchpoints.
2120 If a search parameter value is undefined or empty, it is not included in the returned
2123 The returned array reference may be passed directly to the template parameters.
