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