• If you are trying to use Boolean operators, they must be ALL CAPS: hoi hieu lang - hanh trung ((cua thuong) OR (ca thuong)) hanh van ((ban cau) OR (bang cac))~.
• Adding a wildcard symbol may retrieve word variants: hoi hieu lang - hanh trung ((cua thuong) or (ca thuong)) hanh van ((ban cau) or (bang cac))*.
