multimap find() return 存在多个具有相同键的对象是什么意思?

What does multimap find() return in existence of multple objects with same Key?

multimap find(key) 是否保证 return 是第一个带有键“key”的元素的迭代器? 我在任何地方的文档中都找不到合适的答案。

std::multimap::find(key) returns 任何 元素上的迭代器,其键比较等于 key:

Finds an element with key equivalent to key. If there are several elements with key in the container, any of them may be returned.
