Is there any way for Laravel (4.2 or ???) to support cache partitions? What I mean by this is that I need to be able to flush "regions" of cache at once -- I may not know all the relevant keys involved.

For example, I have a cron job that iterates through some slow API lookups and I cache them, e.g. by the object ids. Laravel doesn't seem to care what key I use: the internal directory structure inside of app/storage/cache/ appears to be arbitrary. What I would like to do clear only part of the cache. E.g. clear a "subdirectory" of the cache, while leaving the other areas in tact.

Another way of putting this is: "can I retrieve all available cache keys that match a given pattern?" E.g. all keys that start with "slow_queries" etc.
