• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach va nang ma hoi. hieu ((ve cam) OR (va cam)) ((xuc va) OR (luc va)) hanh hai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach va nang ma hoi. hieu ((ve cam) or (va cam)) ((xuc va) OR (luc va)) hanh hai cau treo".
