Search for top stylist (4)

I believe the answer is:

comb

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

'search' is the definition.
(I know that comb is a more specific form of search)

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for comb that I've seen before include "Common hair tidier" , "Hair-tidier" , "Red crest on a cock's head" , "For use on hair" , "Systematically search" .)

I've seen this clue in The Mirror and The Daily Express.
