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