• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang ma hoi. ((hieu ve) OR (hieu va)) chat xuc ha thanh lai ((su triet) OR (su viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang ma hoi. ((hieu ve) OR (hieu va)) chat xuc ha thanh lai ((su triet) or (su viet))".
