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