• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (co sach)) y nang ma hoi. ((hieu van) OR (thien van)) cac toc ta danh vi ve triet~.
• Adding a wildcard symbol may retrieve word variants: ((vu sach) or (co sach)) y nang ma hoi. ((hieu van) or (thien van)) cac toc ta danh vi ve triet*.
