• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang ma hoi. ((hieu van) OR (lieu va)) ((lam tuc) OR (luat tuc)) va manh hai cau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang ma hoi. ((hieu van) OR (lieu va)) ((lam tuc) or (luat tuc)) va manh hai cau treo*".
