Search about like a follower (6)
I believe the answer is:
chaser
'follower' is the definition.
(I know that chaser is a type of follower)
'search about' is the wordplay.
'about' indicates an anagram.
'search' is an anagram of 'CHASER'.
'like a' acts as a link.
(Other definitions for chaser that I've seen before include "one in the national hunt" , "One who pursues - one drink after another" , "Racehorse - search (anag)" , "Drink that follows immediately after another one" , "Drink following one of another sort" .)
