174 * $query can be a simple keyword or a complete CCL query
175 * @servers is optional. Defaults to biblioserver as found in koha-conf.xml
176 * $offset - If present, represents the number of records at the beggining to omit. Defaults to 0
177 * $max_results - if present, determines the maximum number of records to fetch. undef is All. defaults to undef.
182 Returns an array consisting of three elements
183 * $error is undefined unless an error is detected
184 * $results is a reference to an array of records.
185 * $total_hits is the number of hits that would have been returned with no limit
187 If an error is returned the two other return elements are undefined. If error itself is undefined
188 the other two elements are always defined

2253 This function returns an array reference that contains the search parameters to be
2254 passed to the Z39.50 search script (z3950_search.pl). The array elements
2255 are hash refs whose keys are name and value, and whose values are the
2256 name of a search parameter, the value of that search parameter and the URL encoded
2257 value of that parameter.
2259 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.
2261 The search parameter values are obtained from the bibliographic record whose
2262 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().
2264 If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g.
2265 a general purpose search argument. In this case, the returned array contains only
2266 entry: the key is 'title' and the value is derived from $matchpoints.
2268 If a search parameter value is undefined or empty, it is not included in the returned
2271 The returned array reference may be passed directly to the template parameters.
