• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach thu) OR (sach thieu)) nang cao hoc. hieu ve cac xuc van anh ((di cua) OR (vai cua)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach thu) OR (sach thieu)) nang cao hoc. hieu ve cac xuc van anh ((di cua) or (vai cua)) cau*".
