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