Before 4.2, if you made a read request to a node that didn't contain part of 
the collection you where searching, it would return 404. Write requests would 
be forwarded to where they belong no matter what node you sent them to, but 
read requests required that node have a part of the collection you were 
accessing.

In 4.2 we added request proxying for this read side case. If a piece of the 
collection you are querying is not found on the node you hit, a simple proxy of 
the request is done to a node that does contain a piece of the collection.
