To search around (6)
I believe the answer is:
ferret
'to search around' is the definition.
('ferret' can be a synonym of 'search around')
This is the entire clue.
(Other definitions for ferret that I've seen before include "Diligent searcher" , "Polecat bred for hunting rats and rabbits" , "Assiduous searcher" , "Animal bred for hunting rats and rabbits" , "Small member of weasel family, good for catching rabbits" .)
