• The words AND, OR and NOT may confuse the search; try adding quotes: "karachi : ((emma OR ((summa OR (summar OR sumar)) OR semma)) OR (sammary OR semmary))~".
• Adding a wildcard symbol may retrieve word variants: karachi : ((emma OR ((summa OR (summar OR sumar)) OR semma)) OR (sammary OR semmary))*.
