+$arrayref = z3950_search_args($matchpoints)
+
+This function returns an array reference that contains the search parameters to be
+passed to the Z39.50 search script (z3950_search.pl). The array elements
+are hash refs whose keys are name, value and encvalue, and whose values are the
+name of a search parameter, the value of that search parameter and the URL encoded
+value of that parameter.
+
+The search parameter names are lccn, isbn, issn, title, author, dewey and subject.
+
+The search parameter values are obtained from the bibliographic record whose
+data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().
+
+If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g.
+a general purpose search argument. In this case, the returned array contains only
+entry: the key is 'title' and the value and encvalue are derived from $matchpoints.
+
+If a search parameter value is undefined or empty, it is not included in the returned
+array.
+
+The returned array reference may be passed directly to the template parameters.
