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