• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang ma hoi. hieu ((va cam) OR (va cao)) luc va thanh ((vi cua) OR (di cua)) vat.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang ma hoi. hieu ((va cam) OR (va cao)) luc va thanh ((vi cua) or (di cua)) vat".
