• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - ((((hanh trang) OR (canh tranh))) OR (thanh trung)) cua nhung phuong san van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - ((((hanh trang) OR (canh tranh))) or (thanh trung)) cua nhung phuong san van ban~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - ((((hanh trang) OR (canh tranh))) or (thanh trung)) cua nhung phuong san van ban*.
