170 * $query can be a simple keyword or a complete CCL query

172 * $offset - If present, represents the number of records at the beginning to omit. Defaults to 0
173 * $max_results - if present, determines the maximum number of records to fetch. undef is All. defaults to undef.

2417 name of a search parameter, the value of that search parameter and the URL encoded
2418 value of that parameter.
