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

2414 are hash refs whose keys are name and value, and whose values are the
2415 name of a search parameter, the value of that search parameter and the URL encoded
2416 value of that parameter.
2418 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.

2421 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().

2424 a general purpose search argument. In this case, the returned array contains only
2425 entry: the key is 'title' and the value is derived from $matchpoints.
