• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y nang) OR (ly nang)) xa hoi. thi van cam ((xuc va) OR (thuc vat)) hanh hai cua tre.
• Adding a wildcard symbol may retrieve word variants: tu sach ((y nang) or (ly nang)) xa hoi. thi van cam ((xuc va) or (thuc vat)) hanh hai cua tre*.
