• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach vu) OR (sach tu)) dang ma hoi. hieu ((vu cham) OR (va cam)) xuc va danh hai cau trieu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach vu) OR (sach tu)) dang ma hoi. hieu ((vu cham) or (va cam)) xuc va danh hai cau trieu".
