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