• If you are trying to use Boolean operators, they must be ALL CAPS: karachi : ((summa OR suma) OR (kumary OR ((sumar OR summar) OR samar))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "karachi : ((summa OR suma) OR (kumary OR ((sumar OR summar) OR samar)))".
• Adding a wildcard symbol may retrieve word variants: karachi : ((summa OR suma) OR (kumary OR ((sumar OR summar) OR samar)))*.
