Search in Tuscany (4)
I believe the answer is:
scan
'search' is the definition.
(I know that scan is a more specific form of the action search)
'in tuscany' is the wordplay.
'in' says the answer is hidden in the clue.
'SCAN' can be found hidden inside 'tuscany'.
(Other definitions for scan that I've seen before include "Peruse, scrutinise" , "Glance negligently at" , "Survey; screen" , "Traverse with a detector" , "Run over" .)
