"A search deque is a data structure with constant-time insertion and removal of elements at both ends, and constant-time membership tests. Inserting an element more than once has no effect. Search deques implement all deque operations in terms of an underlying deque, and membership testing with " { $link deque-member? } " is implemented with an underlying assoc. Search deques are defined in the " { $vocab-link "search-deques" } " vocabulary."
