147 This function provides a simple search API on the bibliographic catalog
153 * $query can be a simple keyword or a complete CCL query
154 * @servers is optional. Defaults to biblioserver as found in koha-conf.xml
155 * $offset - If present, represents the number of records at the beginning to omit. Defaults to 0
156 * $max_results - if present, determines the maximum number of records to fetch. undef is All. defaults to undef.
157 * %options is optional. (e.g. "skip_normalize" allows you to skip changing : to = )
162 Returns an array consisting of three elements
163 * $error is undefined unless an error is detected
164 * $results is a reference to an array of records.
165 * $total_hits is the number of hits that would have been returned with no limit
167 If an error is returned the two other return elements are undefined. If error itself is undefined
168 the other two elements are always defined

2249 system preferences and configuration variables to properly create the
2250 MARC::Record object.

2253 data. If we are using DOM, then it has to be MARCXML.
