• If you are trying to use Boolean operators, they must be ALL CAPS: karachi : ((umar OR emma) OR ((summa OR (saman OR zaman)) OR (summarry OR sumar))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "karachi : ((umar OR emma) OR ((summa OR (saman OR zaman)) OR (summarry OR sumar)))".
