 ### Outputs
 
-* `cache-hit` - A boolean value to indicate an exact match was found for the key.
+* `cache-hit` - A string value to indicate an exact match was found for the key.
-
+  * If there's a cache hit, this will be 'true' or 'false' to indicate if there's an exact match for `key`.
-    > **Note** `cache-hit` will only be set to `true` when a cache hit occurs for the exact `key` match. For a partial key match via `restore-keys` or a cache miss, it will be set to `false`.
+  * If there's a cache miss, this will be an empty string.
