Search for doctor at border (6)

Ross

I believe the answer is:

dredge

'search' is the definition.
(dredging is a kind of searching)

'doctor at border' is the wordplay.
'doctor' becomes 'dr' (abbreviation).
'at' is a charade indicator (letters next to each other).
'border' becomes 'edge' (synonyms).
'dr'+'edge'='DREDGE'

'for' is the link.

(Other definitions for dredge that I've seen before include "Drag up" , "(Of harbour or river) make deeper" , "Scoop up mud and silt from harbour bottom" , "Dig up mud from river or canal bed" , "Clean out the bed of a river or harbour" .)

I've seen this clue in The Mirror.
