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