155 * $query can be a simple keyword or a complete CCL query
156 * @servers is optional. Defaults to biblioserver as found in koha-conf.xml
157 * $offset - If present, represents the number of records at the beggining to omit. Defaults to 0
158 * $max_results - if present, determines the maximum number of records to fetch. undef is All. defaults to undef.
163 Returns an array consisting of three elements
164 * $error is undefined unless an error is detected
165 * $results is a reference to an array of records.
166 * $total_hits is the number of hits that would have been returned with no limit
168 If an error is returned the two other return elements are undefined. If error itself is undefined
169 the other two elements are always defined
