• Performing a fuzzy search may retrieve terms with similar spellings: thep thiet tach - ((hanh truong) OR (manh truong)) ((dai hang) or (dai thang)) nguon dan tran cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thep thiet tach - ((hanh truong) OR (manh truong)) ((dai hang) OR (dai thang)) nguon dan tran cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thep thiet tach - ((hanh truong) OR (manh truong)) ((dai hang) or (dai thang)) nguon dan tran cau*".
