2590 This function returns an array reference that contains the search parameters to be

2592 are hash refs whose keys are name, value and encvalue, and whose values are the
2593 name of a search parameter, the value of that search parameter and the URL encoded
2594 value of that parameter.
2595
2596 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.
2597
2598 The search parameter values are obtained from the bibliographic record whose
2599 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().

2601 If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g.
2602 a general purpose search argument. In this case, the returned array contains only
2603 entry: the key is 'title' and the value and encvalue are derived from $matchpoints.
2604
2605 If a search parameter value is undefined or empty, it is not included in the returned
2606 array.
