Look for fallen arches (6)

I believe the answer is:

'look for' is the definition.
(synonyms)

'fallen arches' is the wordplay.
'fallen' indicates an anagram.
'arches' with letters rearranged gives 'SEARCH'.

(Other definitions for search that I've seen before include "Seek carefully (for something)" , "Probe" , "Look thoroughly to find something" , "Scour, seek" , "What examiners do" .)
