can results of views be reused in other views?

[Vikram Bhandoh]

Hi,

I'm trying to figure out if results of one view can be reused in  
another?
I have a situation where one of my views does map/reduce and generates  
some data for me.

Here is the example, Post and Tags for posts. (two different documents  
linked by post._id and tag.post)
My view returns the number of tags for the post, keyed on post._id

Now I want a view where I want to return the post and the number of  
tags in the post.
preferably without having to copy all the code.

Many thanks,
Vikram
