2452 name of a search parameter, the value of that search parameter and the URL encoded
2453 value of that parameter.
2454
2455 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.

2457 The search parameter values are obtained from the bibliographic record whose
2458 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().

2460 If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g.
2461 a general purpose search argument. In this case, the returned array contains only
2462 entry: the key is 'title' and the value and encvalue are derived from $matchpoints.
2463
2464 If a search parameter value is undefined or empty, it is not included in the returned
2465 array.
