• If you are trying to use Boolean operators, they must be ALL CAPS: thien ((((nhien lang) OR (hieu lang))) OR (nhieu tang)) - hang hang va tong cong vang toan cau~.
• Adding a wildcard symbol may retrieve word variants: thien ((((nhien lang) or (hieu lang))) or (nhieu tang)) - hang hang va tong cong vang toan cau*.
