2589 This function returns an array reference that contains the search parameters to be
2590 passed to the Z39.50 search script (z3950_search.pl). The array elements
2591 are hash refs whose keys are name, value and encvalue, and whose values are the
2592 name of a search parameter, the value of that search parameter and the URL encoded
2593 value of that parameter.
2594
2595 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.
2596
2597 The search parameter values are obtained from the bibliographic record whose
2598 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().
2599
2600 If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g.
2601 a general purpose search argument. In this case, the returned array contains only
2602 entry: the key is 'title' and the value and encvalue are derived from $matchpoints.
2603
2604 If a search parameter value is undefined or empty, it is not included in the returned
2605 array.
2606
2607 The returned array reference may be passed directly to the template parameters.
