The whole clue is the definition (& lit or double definition).
How the clue works
The whole clue works as a cryptic definition: "sure indications" gives you the literal meaning, while the nudge about "two of which are apparent in this puzzle" is a self-referential wink — somewhere in the grid there are two plus symbols (+ +) hiding in plain sight. There's no separate wordplay to untangle; the definition and the cheeky hint are doing the same job at once.
