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

2297 This function returns an array reference that contains the search parameters to be
2298 passed to the Z39.50 search script (z3950_search.pl). The array elements
2299 are hash refs whose keys are name and value, and whose values are the
2300 name of a search parameter, the value of that search parameter and the URL encoded
2301 value of that parameter.
2303 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.
2305 The search parameter values are obtained from the bibliographic record whose
2306 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().
2308 If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g.
2309 a general purpose search argument. In this case, the returned array contains only
2310 entry: the key is 'title' and the value is derived from $matchpoints.
2312 If a search parameter value is undefined or empty, it is not included in the returned
2315 The returned array reference may be passed directly to the template parameters.
