• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang xa hoi. lieu va cac ((xuc ban) OR (duc van)) anh hai ((cua tre) OR (su triet)).
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. lieu va cac ((xuc ban) or (duc van)) anh hai ((cua tre) or (su triet))*.
