• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty nang ma hoi. ((hieu ve) OR (hieu va)) cam tuc va ((danh va) OR (danh di)) cua tre~.
• Adding a wildcard symbol may retrieve word variants: vu sach ty nang ma hoi. ((hieu ve) or (hieu va)) cam tuc va ((danh va) or (danh di)) cua tre*.
