• Performing a fuzzy search may retrieve terms with similar spellings: hoc thieu xanh - hanh ((((tinh cua) OR (tinh chat))) or (trinh cua)) nhung cong dan toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - hanh ((((tinh cua) OR (tinh chat))) OR (trinh cua)) nhung cong dan toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh ((((tinh cua) OR (tinh chat))) or (trinh cua)) nhung cong dan toan cao*".
