Searched around area regularly visited by ghosts (7)
I believe the answer is:
haunted
'regularly visited by ghosts' is the definition.
(haunted by ghosts)
'searched around area' is the wordplay.
'searched' becomes 'hunted'.
'around' is an insertion indicator.
'area' becomes 'a' (maths abbreviation).
'hunted' going around 'a' is 'HAUNTED'.
(Other definitions for haunted that I've seen before include "Worried" , "with the ghost still around?" , "Possessed" , "Beset by spirits" , "Frequented by ghosts" .)
