2104 name of a search parameter, the value of that search parameter and the URL encoded
2105 value of that parameter.

2107 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.

2110 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().

2113 a general purpose search argument. In this case, the returned array contains only
2114 entry: the key is 'title' and the value and encvalue are derived from $matchpoints.

2116 If a search parameter value is undefined or empty, it is not included in the returned
2117 array.
