Since there isn't respositories for value objects. How can I load all value objects?

Suppose we are modeling a blog application and we have this classes:

Post (Entity)
Comment (Value object)
Tag (Value object)
PostsRespository (Respository)

I Know that when I save a new post, its tags are saving with it in the same table. But how could I load all tags of all posts. Has PostsRespository got a method to load all tags? I usually do it, but I want to know others opinions
