• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach kem) OR (sach ty)) nang ((o hoi) OR (x ho)). hieu ve cam luoc can hanh em cua tre~.
• Adding a wildcard symbol may retrieve word variants: te ((sach kem) or (sach ty)) nang ((o hoi) or (x ho)). hieu ve cam luoc can hanh em cua tre*.
