• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y tang tai hoc. hieu ve cham xuc ((van hanh) or (van anh)) ((vi cua) OR (vai cua)) tuc~".
• Adding a wildcard symbol may retrieve word variants: su sach y tang tai hoc. hieu ve cham xuc ((van hanh) or (van anh)) ((vi cua) OR (vai cua)) tuc*.
