151 * $query can be a simple keyword or a complete CCL query
152 * @servers is optional. Defaults to biblioserver as found in koha-conf.xml
153 * $offset - If present, represents the number of records at the beggining to omit. Defaults to 0
154 * $max_results - if present, determines the maximum number of records to fetch. undef is All. defaults to undef.
159 * $error is a empty unless an error is detected
160 * \@results is an array of records.
161 * $total_hits is the number of hits that would have been returned with no limit
