• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky ((nang x) OR (lang van)) hoi. hieu va cham xuc van hanh ((vi cua) OR (vai cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky ((nang x) or (lang van)) hoi. hieu va cham xuc van hanh ((vi cua) OR (vai cua)) te".
