172 * $query can be a simple keyword or a complete CCL query
173 * @servers is optional. Defaults to biblioserver as found in koha-conf.xml
174 * $offset - If present, represents the number of records at the beginning to omit. Defaults to 0
175 * $max_results - if present, determines the maximum number of records to fetch. undef is All. defaults to undef.
176 * %options is optional. (e.g. "skip_normalize" allows you to skip changing : to = )
179 =item C<Return:>
181 Returns an array consisting of three elements
182 * $error is undefined unless an error is detected
183 * $results is a reference to an array of records.
184 * $total_hits is the number of hits that would have been returned with no limit
186 If an error is returned the two other return elements are undefined. If error itself is undefined
187 the other two elements are always defined

2498 Given raw data from a searchengine result set, return a MARC::Record object
2500 This helper function is needed to take into account all the involved
2501 system preferences and configuration variables to properly create the
2502 MARC::Record object.
2504 If we are using GRS-1, then the raw data we get from Zebra should be USMARC
2505 data. If we are using DOM, then it has to be MARCXML.
2507 If we are using elasticsearch, it'll already be a MARC::Record and this
2508 function needs a new name.
