• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan ((((tran hua) OR (tran duc))) OR (tan hua)) ren kong john bonn ana ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((((tran hua) OR (tran duc))) or (tan hua)) ren kong john bonn ana ;*".
