• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tu ((nang mai) OR (nang ma)) hoi. hieu ve cac ((luc van) OR (xuc ban)) thanh san cua tuc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tu ((nang mai) OR (nang ma)) hoi. hieu ve cac ((luc van) or (xuc ban)) thanh san cua tuc".
