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