• Performing a fuzzy search may retrieve terms with similar spellings: theo chu sang - ((((hanh mang) OR (nhanh mang))) or (nhanh lang)) cua thong cong dan toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu sang - ((((hanh mang) OR (nhanh mang))) OR (nhanh lang)) cua thong cong dan toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu sang - ((((hanh mang) OR (nhanh mang))) or (nhanh lang)) cua thong cong dan toan ban*".
