• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((tang ma) OR (tang van)) hoi. hieu va cham tuc va thanh tai ((su triet) OR (su viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((tang ma) OR (tang van)) hoi. hieu va cham tuc va thanh tai ((su triet) or (su viet))".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((tang ma) OR (tang van)) hoi. hieu va cham tuc va thanh tai ((su triet) or (su viet))*.
