2501
2502 This function returns an array reference that contains the search parameters to be
2503 passed to the Z39.50 search script (z3950_search.pl). The array elements
2504 are hash refs whose keys are name, value and encvalue, and whose values are the
2505 name of a search parameter, the value of that search parameter and the URL encoded
2506 value of that parameter.
2507
2508 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.
2509
2510 The search parameter values are obtained from the bibliographic record whose
2511 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().
2512
2513 If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g.
2514 a general purpose search argument. In this case, the returned array contains only
2515 entry: the key is 'title' and the value and encvalue are derived from $matchpoints.
2516
2517 If a search parameter value is undefined or empty, it is not included in the returned
2518 array.
2519
2520 The returned array reference may be passed directly to the template parameters.
