• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly hang xa hoi. ((hieu va) OR (lieu va)) cham luu ban hanh vi ((su triet) OR (ve triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly hang xa hoi. ((hieu va) OR (lieu va)) cham luu ban hanh vi ((su triet) or (ve triet))".
• Adding a wildcard symbol may retrieve word variants: tu sach ly hang xa hoi. ((hieu va) OR (lieu va)) cham luu ban hanh vi ((su triet) or (ve triet))*.
