• If you are trying to use Boolean operators, they must be ALL CAPS: karachi : ((umma OR emma) OR (((summa OR samma) OR (sumbar OR summahr)) OR (summarh OR summaryh))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "karachi : ((umma OR emma) OR (((summa OR samma) OR (sumbar OR summahr)) OR (summarh OR summaryh)))".
