• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y mang xa hoi. hieu va cau ((((xuc van) OR (vuc van))) OR (duc van)) anh ve dat tren.
• Adding a wildcard symbol may retrieve word variants: te sach y mang xa hoi. hieu va cau ((((xuc van) or (vuc van))) or (duc van)) anh ve dat tren*.
