key in the cache group. If the cache is hit (success) then the contents
are returned.
On failure, the number of cache misses will be incremented.

| $key | integer | string | What the contents in the cache are called |
| $group | string | Where the cache contents are grouped |
| $force | string | Whether to force a refetch rather than relying on the local cache (default is false) |
