Search fine men to date (6)
I believe the answer is:
forage
'search' is the definition.
(I know that forage is a type of search)
'fine men to date' is the wordplay.
'fine' becomes 'f' (abbreviation).
'men' becomes 'OR' (military abbreviation for Other Ranks).
'to date' becomes 'age' (both can mean to get older).
'f'+'or'+'age'='FORAGE'
(Other definitions for forage that I've seen before include "sort of cap" , "Hunt for food or provisions" , "Military raid" , "Collect food" , "Go searching, perhaps for food" .)
