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