I search out purser (7)

Ross

I believe the answer is:

cashier

'purser' is the definition.
(thesaurus)

'i search out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'i'+'search'='isearch'
'isearch' is an anagram of 'CASHIER'.

(Other definitions for cashier that I've seen before include "Drum out of the army" , "One handles the money" , "till tender?" , "Bank teller" , "Remove from service" .)

I've seen this clue in The Telegraph.
