• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - thanh tung tuan hung ((((cong ban) OR (cong bang))) OR (cong tan)) khan cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - thanh tung tuan hung ((((cong ban) OR (cong bang))) or (cong tan)) khan cap~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - thanh tung tuan hung ((((cong ban) OR (cong bang))) or (cong tan)) khan cap*.
