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