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