<p>This option setter specifies if the unordered hook should offer room to store another link to another node with the same key. Storing this link will speed up lookups and insertions on <a class="link" href="unordered_multiset.html" title="Class template unordered_multiset">unordered_multiset</a> containers with a great number of elements with the same key. </p>
