• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sanh trong ((phong khi) OR (phong thi)) đong luc ) OR ( thu sach tinh khong khi đong luc )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sanh trong ((phong khi) OR (phong thi)) đong luc ) or ( thu sach tinh khong khi đong luc ))".
• Adding a wildcard symbol may retrieve word variants: (( thu sanh trong ((phong khi) OR (phong thi)) đong luc ) or ( thu sach tinh khong khi đong luc ))*.
