• Performing a fuzzy search may retrieve terms with similar spellings: doc ((hieu xanh) OR (hieu nganh)) - ((hanh trinh) or (canh tranh)) cap thuong dong dan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu xanh) OR (hieu nganh)) - ((hanh trinh) OR (canh tranh)) cap thuong dong dan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu xanh) OR (hieu nganh)) - ((hanh trinh) or (canh tranh)) cap thuong dong dan toan cau".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu xanh) OR (hieu nganh)) - ((hanh trinh) or (canh tranh)) cap thuong dong dan toan cau*.
