Search and identify a savoury snack... (10)

I believe the answer is:

fishfinger

I'm a little stuck... Click here to teach me more about this clue!

'a savoury snack' is the definition.
The definition suggests a singular noun which matches the answer.

'search and identify' is the wordplay.
'search' becomes 'fish' (fishing is a kind of searching).
'and' is a charade indicator (letters next to each other).
'identify' becomes 'finger' (I've seen this before).
'fish'+'finger'='FISHFINGER'

Can you help me to learn more?

(Another definition for fishfinger that I've seen is " snack food".)

I've seen this clue in The Daily Express.
