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