erlang - Erlang：从列表中查找单词并返回 True

Question

如何使函数在列表中搜索单词并在列表中的单词返回 true。

例子 ：

find(string) ->
    List = ["bye", "hello", "hi"],
    case string in List of
        true ->
            true;
        _ ->
            false
    end.

find("hi there, how are you today?").

文字是：“嗨，你今天好吗？”

它应该在列表中返回 true cuz hi。
