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