• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu nganh) OR (ha tinh)) - canh tranh cua bang cong ((vang tuan) OR (quang tuan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu nganh) or (ha tinh)) - canh tranh cua bang cong ((vang tuan) OR (quang tuan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu nganh) or (ha tinh)) - canh tranh cua bang cong ((vang tuan) OR (quang tuan)) cau*.
