• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu sang) OR (chieu sach)) - hanh mang luan thong tuong dan ((han tap) or (nhan tai))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu sach)) - hanh mang luan thong tuong dan ((han tap) OR (nhan tai))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) OR (chieu sach)) - hanh mang luan thong tuong dan ((han tap) or (nhan tai))*".
