Sift through (4)

I think it could be either:

comb

cull

'sift through' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for cull that I've seen before include "Selectively slaughter" , "Kill surplus animals in herd" , "Remove from herd" , "Pick (best); kill off (weakest)" , "Select and destroy inferior specimens" .)

I've seen this clue in the LA Times and The New York Times.
