• Performing a fuzzy search may retrieve terms with similar spellings: doc ((hieu manh) OR (hieu nganh)) - hanh trung ((cap tong) or (cap hoang)) cong dang thanh cat~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu manh) OR (hieu nganh)) - hanh trung ((cap tong) OR (cap hoang)) cong dang thanh cat*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu manh) OR (hieu nganh)) - hanh trung ((cap tong) or (cap hoang)) cong dang thanh cat*".
