• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach v) OR (sach va)) lang van hoi. hieu ((ve cam) OR (ve cac)) xuc va hanh di cua viet~.
• Adding a wildcard symbol may retrieve word variants: te ((sach v) or (sach va)) lang van hoi. hieu ((ve cam) or (ve cac)) xuc va hanh di cua viet*.
