• If you are trying to use Boolean operators, they must be ALL CAPS: karachi : ((umma OR ummah) OR (((summa OR summah) OR samma) OR (semma OR emma))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "karachi : ((umma OR ummah) OR (((summa OR summah) OR samma) OR (semma OR emma)))".
