• If you are trying to use Boolean operators, they must be ALL CAPS: karachi : (umma OR ((sma OR suman) OR ((semmar OR summar) OR (summay OR ssummay)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "karachi : (umma OR ((sma OR suman) OR ((semmar OR summar) OR (summay OR ssummay))))".
