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