How the Finder works?

The Finder uses the SCAN command when available (Redis 2.8.0+) and fallback on KEYS otherwise. In order to not overload the user Redis server the SCAN is limited to return the first 5000 keys that match the specified search pattern.

Note: the KEYS fallback will be dropped as soon as 90% of our users will have upgraded to at least Redis 2.8.0.
