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