• Performing a fuzzy search may retrieve terms with similar spellings: doc ((hieu xanh) or (((hieu nganh) OR (vien nganh)))) - thanh thuong xay dung cong ty va ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu xanh) OR (((hieu nganh) OR (vien nganh)))) - thanh thuong xay dung cong ty va ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu xanh) or (((hieu nganh) OR (vien nganh)))) - thanh thuong xay dung cong ty va ban*".
