Warning about a good search around (6)
I believe the answer is:
forage
'search around' is the definition.
'forage' can be an answer for 'search' (I've seen this before). I am not certain of the 'around' bit.
'warning about a good' is the wordplay.
'warning' becomes 'fore' (I've seen this in other clues).
'about' indicates putting letters inside.
'good' becomes 'g' (abbreviation).
'a'+'g'='ag'
'fore' enclosing 'ag' is 'FORAGE'.
Can you help me to learn more?
(Other definitions for forage that I've seen before include "Hunt for food or provisions" , "Search widely for food" , "Seek for food" , "look around" , "Collect food" .)
