• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((nang cao) OR (tang van)) hoi. hieu ve chat xuc ban ((hang vi) OR (hang di)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((nang cao) or (tang van)) hoi. hieu ve chat xuc ban ((hang vi) OR (hang di)) cua tre*".
