• If you are trying to use Boolean operators, they must be ALL CAPS: ((nhung tri) OR (nhung thi)) que lang. ((biet tran) OR (bien tran)) trong ban than.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nhung tri) or (nhung thi)) que lang. ((biet tran) OR (bien tran)) trong ban than".
