2259 This function returns an array reference that contains the search parameters to be
2260 passed to the Z39.50 search script (z3950_search.pl). The array elements
2261 are hash refs whose keys are name and value, and whose values are the
2262 name of a search parameter, the value of that search parameter and the URL encoded
2263 value of that parameter.
2264
2265 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.
2266
2267 The search parameter values are obtained from the bibliographic record whose
2268 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().
2269
2270 If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g.
2271 a general purpose search argument. In this case, the returned array contains only
2272 entry: the key is 'title' and the value is derived from $matchpoints.
2273
2274 If a search parameter value is undefined or empty, it is not included in the returned
2275 array.
2276
2277 The returned array reference may be passed directly to the template parameters.
