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
