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