• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((nang ma) OR (tang ma)) hoa. hieu va cham ((xuc cam) OR (phuc cam)) hang dau ca viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((nang ma) or (tang ma)) hoa. hieu va cham ((xuc cam) OR (phuc cam)) hang dau ca viet".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((nang ma) or (tang ma)) hoa. hieu va cham ((xuc cam) OR (phuc cam)) hang dau ca viet*.
