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

2239 This function returns an array reference that contains the search parameters to be
2240 passed to the Z39.50 search script (z3950_search.pl). The array elements
2241 are hash refs whose keys are name, value and encvalue, and whose values are the
2242 name of a search parameter, the value of that search parameter and the URL encoded
2243 value of that parameter.
2245 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.
2247 The search parameter values are obtained from the bibliographic record whose
2248 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().
2250 If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g.
2251 a general purpose search argument. In this case, the returned array contains only
2252 entry: the key is 'title' and the value and encvalue are derived from $matchpoints.
2254 If a search parameter value is undefined or empty, it is not included in the returned
2257 The returned array reference may be passed directly to the template parameters.
