• If you are trying to use Boolean operators, they must be ALL CAPS: karachi : ((umma OR (spmma OR ((semmar OR summar) OR summary))) OR ((sammah OR semmah) OR spmmah)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "karachi : ((umma OR (spmma OR ((semmar OR summar) OR summary))) OR ((sammah OR semmah) OR spmmah))".
