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