DescriptionFor more information on subscription_ids format check EP (http://etherpad.osuosl.org/moin-mail) Section 1.3
The `subscribed_items` meta was not removed ATM, since it involves a lot of other changes unrelated to current cr.

What is the use of an index if you can't search for a value? Please read the whoosh documentation again about the meaning of the "stored" attribute.

Add all the information to the subscription index you need. You don't want to read all users just for fun.

In Python we use duck-typing. So please explain why this check is needed.

If we will be having some other objects that will act like item or passing any other iterable object instead of Results, then I can remove the check.
