146 This function provides a simple search API on the bibliographic catalog
152 * $query can be a simple keyword or a complete CCL query
153 * @servers is optional. Defaults to biblioserver as found in koha-conf.xml
154 * $offset - If present, represents the number of records at the beggining to omit. Defaults to 0
155 * $max_results - if present, determines the maximum number of records to fetch. undef is All. defaults to undef.
160 Returns an array consisting of three elements
161 * $error is undefined unless an error is detected
162 * $results is a reference to an array of records.
163 * $total_hits is the number of hits that would have been returned with no limit
165 If an error is returned the two other return elements are undefined. If error itself is undefined
166 the other two elements are always defined
