• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu sach) or (chieu sang)) - ((hanh truong) OR (manh truong)) duc dung thuong dan toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chieu sang)) - ((hanh truong) OR (manh truong)) duc dung thuong dan toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (chieu sang)) - ((hanh truong) OR (manh truong)) duc dung thuong dan toan ban*".
