set-max-null-count! parse-options null-countprocedure

When parsing a sentence, the parser will find all solutions having the minimum number of null links. It carries out its search in the range of null link counts between min-null-count and max-null-count. By default, the minimum and maximum number of null links is 0, so null links are not used.
