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

2199 This function returns an array reference that contains the search parameters to be
2200 passed to the Z39.50 search script (z3950_search.pl). The array elements
2201 are hash refs whose keys are name and value, and whose values are the
2202 name of a search parameter, the value of that search parameter and the URL encoded
2203 value of that parameter.
2205 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.
2207 The search parameter values are obtained from the bibliographic record whose
2208 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().
2210 If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g.
2211 a general purpose search argument. In this case, the returned array contains only
2212 entry: the key is 'title' and the value is derived from $matchpoints.
2214 If a search parameter value is undefined or empty, it is not included in the returned
2217 The returned array reference may be passed directly to the template parameters.

2345 Given raw data from a searchengine result set, return a MARC::Record object

2352 data. If we are using DOM, then it has to be MARCXML.
