• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach kem) OR (sac ky)) lang ha hoi. lieu va cao cua ban hanh hai ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach kem) or (sac ky)) lang ha hoi. lieu va cao cua ban hanh hai ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: tu ((sach kem) or (sac ky)) lang ha hoi. lieu va cao cua ban hanh hai ((cua tre) OR (cua triet))*.
