• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach v ((nang ma) OR (nang cao)) hoi. hieu ((ve cam) OR (va cam)) duc manh thang moi cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach v ((nang ma) OR (nang cao)) hoi. hieu ((ve cam) or (va cam)) duc manh thang moi cua tu".
