• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang x hoi. hieu ((ve cam) OR (ve cac)) luc van anh kem ((cuu tre) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang x hoi. hieu ((ve cam) OR (ve cac)) luc van anh kem ((cuu tre) or (cau treo))".
• Adding a wildcard symbol may retrieve word variants: te sach y nang x hoi. hieu ((ve cam) OR (ve cac)) luc van anh kem ((cuu tre) or (cau treo))*.
