You then iterate over the list from the stories with the given tag, putting each into the map using the ID of the story as the key.

You could use a List or a Map to implement the relationship; however, a Map offers the advantage that it can provide fast lookup given, say, the book catalog number as the key.
可以用List或Map实现这个关系；但是Map提供的优势是它能提供快速的查询，也就是说用图书目录编号作为键。
For example, you can access a list element with zget("/request/myList#3"), or the value of key within a map using zget("/request/myMap#key").
例如，可以通过zget("/request/myList#3")访问列表元素，或使用 zget("/request/myMap#key") 访问映射内部的 key 的值。
A global reverse index is simply a design where you create a map whose key is the search term, and the value is the list of keys containing an attribute with that search term.
一个全局反向索引仅仅是一个设计，其中创建的映射的键是搜索关键词，且其值是包含属性与搜索关键词的键列表。
