• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((nhieu tang) OR (chiet tach)) - hanh trong van dung trong van ((thanh cao) OR (thanh cac))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((nhieu tang) or (chiet tach)) - hanh trong van dung trong van ((thanh cao) OR (thanh cac))*".
