A prototypical example setting is that of tweets. A tweet is a set of words, and Twitter emits about half a billion tweets per day. Our solution makes it possible to efficiently maintain the top-$k$ most similar tweets from a pair of rapid Twitter streams, e.g., to discover similar trends in two cities if the streams concern cities.\n  Using a sliding window model, the top-$k$ result changes as new sets in the stream enter the window or existing ones leave the window.
