• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu xanh) OR (chieu xanh)) - hanh trinh cap ((thuong cong) OR (thong cong)) tan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu xanh) OR (chieu xanh)) - hanh trinh cap ((thuong cong) or (thong cong)) tan toan ban~".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu xanh) OR (chieu xanh)) - hanh trinh cap ((thuong cong) or (thong cong)) tan toan ban*.
