• Performing a fuzzy search may retrieve terms with similar spellings: karachi : (emma OR (summa OR ((summar OR (sugar OR skumar)) OR (lsummaryy OR lsummary))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: karachi : (emma OR (summa OR ((summar OR (sugar OR skumar)) OR (lsummaryy OR lsummary)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "karachi : (emma OR (summa OR ((summar OR (sugar OR skumar)) OR (lsummaryy OR lsummary))))".
• Adding a wildcard symbol may retrieve word variants: karachi : (emma OR (summa OR ((summar OR (sugar OR skumar)) OR (lsummaryy OR lsummary))))*.
