• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chu xanh) OR (chua xang)) - hanh thong va nhung cong ((van toan) OR (manh toan)) cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chua xang)) - hanh thong va nhung cong ((van toan) or (manh toan)) cau*.
