• If you are trying to use Boolean operators, they must be ALL CAPS: karachi : ((umma OR ((semma OR suma) OR samma)) OR (summah OR semmah)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "karachi : ((umma OR ((semma OR suma) OR samma)) OR (summah OR semmah))".
• Adding a wildcard symbol may retrieve word variants: karachi : ((umma OR ((semma OR suma) OR samma)) OR (summah OR semmah))*.
