• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang xa hoi. hieu ((((ve cai) OR (va cai))) OR (va cam)) duc va dinh dai cua tu.
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. hieu ((((ve cai) or (va cai))) or (va cam)) duc va dinh dai cua tu*.
