2563 This function returns an array reference that contains the search parameters to be
2564 passed to the Z39.50 search script (z3950_search.pl). The array elements
2565 are hash refs whose keys are name, value and encvalue, and whose values are the
2566 name of a search parameter, the value of that search parameter and the URL encoded
2567 value of that parameter.
2568
2569 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.
2570
2571 The search parameter values are obtained from the bibliographic record whose
2572 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().

2574 If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g.
2575 a general purpose search argument. In this case, the returned array contains only
2576 entry: the key is 'title' and the value and encvalue are derived from $matchpoints.
2577
2578 If a search parameter value is undefined or empty, it is not included in the returned
2579 array.
