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