156
157 * $query can be a simple keyword or a complete CCL query
158 * @servers is optional. Defaults to biblioserver as found in koha-conf.xml
159 * $offset - If present, represents the number of records at the beginning to omit. Defaults to 0
160 * $max_results - if present, determines the maximum number of records to fetch. undef is All. defaults to undef.
161 * %options is optional. (e.g. "skip_normalize" allows you to skip changing : to = )
162
163
164 =item C<Return:>
165
166 Returns an array consisting of three elements
167 * $error is undefined unless an error is detected
168 * $results is a reference to an array of records.
169 * $total_hits is the number of hits that would have been returned with no limit
170
171 If an error is returned the two other return elements are undefined. If error itself is undefined
172 the other two elements are always defined

2195 This function returns an array reference that contains the search parameters to be
2196 passed to the Z39.50 search script (z3950_search.pl). The array elements
2197 are hash refs whose keys are name and value, and whose values are the
2198 name of a search parameter, the value of that search parameter and the URL encoded
2199 value of that parameter.
2200
2201 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.
2202
2203 The search parameter values are obtained from the bibliographic record whose
2204 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().
2205
2206 If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g.
2207 a general purpose search argument. In this case, the returned array contains only
2208 entry: the key is 'title' and the value is derived from $matchpoints.
2209
2210 If a search parameter value is undefined or empty, it is not included in the returned
2211 array.
2212
2213 The returned array reference may be passed directly to the template parameters.
