• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y ((nang xa) OR (nang ma)) hoi. lieu va lam ((luc va) OR (tuc va)) hanh di cuu tre.
• Adding a wildcard symbol may retrieve word variants: tu sach y ((nang xa) or (nang ma)) hoi. lieu va lam ((luc va) or (tuc va)) hanh di cuu tre*.
