2604 name of a search parameter, the value of that search parameter and the URL encoded
2605 value of that parameter.

2607 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.

2610 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().

2613 a general purpose search argument. In this case, the returned array contains only
2614 entry: the key is 'title' and the value and encvalue are derived from $matchpoints.

2616 If a search parameter value is undefined or empty, it is not included in the returned
