2456 This function returns an array reference that contains the search parameters to be
2457 passed to the Z39.50 search script (z3950_search.pl). The array elements
2458 are hash refs whose keys are name, value and encvalue, and whose values are the
2459 name of a search parameter, the value of that search parameter and the URL encoded
2460 value of that parameter.
2462 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.
2464 The search parameter values are obtained from the bibliographic record whose
2465 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().
2467 If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g.
2468 a general purpose search argument. In this case, the returned array contains only
2469 entry: the key is 'title' and the value and encvalue are derived from $matchpoints.
2471 If a search parameter value is undefined or empty, it is not included in the returned
2472 array.
2474 The returned array reference may be passed directly to the template parameters.
