1. A machine-implemented method, comprising: receiving an indication of a request from a user to view a stream associated with the user; generating a request for one or more items, of a plurality of items, that are visible to the user for display within the stream, wherein each of the plurality of items includes one or more user tokens up to a threshold number of user tokens, the one or more user tokens indicate viewability of the item by users associated with the one or more user tokens, wherein the request comprises a search query identifying search criteria including one or more tokens up to a threshold number of tokens, the one or more tokens includes at least a user token identifying the user, and wherein generating the request comprises: determining that a super followee token is to be included in the search query, the super followee token corresponding to a super followee user that owns an item visible to a number of users that meets a threshold number of users, replacing the super followee token with a super doc token when the included super followee token causes the one or more tokens to exceed the threshold number of tokens, the super doc token identifying a type of item owned by the super followee user; receiving one or more items in response to the request, the one or more items including at least one of the one or more tokens and further being visible to the user; and providing the one or more items for display to the user within the stream in response to the request.

The method of claim 1 , the one or more tokens further including at least one owner token, the owner token identifying a second user associated with the first user.
