• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sai ky) OR (sach y)) nang xa hoi. ((hieu va) OR (hieu qua)) cap nuoc ban anh d ve triet.
• Adding a wildcard symbol may retrieve word variants: tu ((sai ky) or (sach y)) nang xa hoi. ((hieu va) or (hieu qua)) cap nuoc ban anh d ve triet*.
