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 = )

187 the other two elements are always defined

2368 name of a search parameter, the value of that search parameter and the URL encoded
2369 value of that parameter.

2380 If a search parameter value is undefined or empty, it is not included in the returned
