• Performing a fuzzy search may retrieve terms with similar spellings: toc thieu nganh - canh ((tranh cua) OR (doanh cua)) ((dang cong) or (cong cong)) dang van ca~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc thieu nganh - canh ((tranh cua) OR (doanh cua)) ((dang cong) OR (cong cong)) dang van ca*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc thieu nganh - canh ((tranh cua) OR (doanh cua)) ((dang cong) or (cong cong)) dang van ca*".
