• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ly) OR (sach y)) nang ma hoi. hieu va chat huu ban hang vi ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ly) OR (sach y)) nang ma hoi. hieu va chat huu ban hang vi ((cua tre) or (cua triet))".
