• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh tranh cua ((nhung cong) OR (dung cong)) ((tap quan) OR (tac quan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh tranh cua ((nhung cong) or (dung cong)) ((tap quan) OR (tac quan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh tranh cua ((nhung cong) or (dung cong)) ((tap quan) OR (tac quan)) cau*.
