• If you are trying to use Boolean operators, they must be ALL CAPS: tu bach van ((lang ha) OR (long ha)) hoi. hieu ve cam xuc ban hanh vi ((su triet) OR (su viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu bach van ((lang ha) or (long ha)) hoi. hieu ve cam xuc ban hanh vi ((su triet) OR (su viet))".
