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