• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ky tang xa hoi. hieu ((va cao) OR (va cac)) duc manh hanh ((than cua) OR (nhan cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ky tang xa hoi. hieu ((va cao) OR (va cac)) duc manh hanh ((than cua) or (nhan cua)) tre".
