• If you are trying to use Boolean operators, they must be ALL CAPS: ((nhung thoi) OR (nhung gi)) ((quan van) OR (luan van)). thoi huyen truc lap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nhung thoi) or (nhung gi)) ((quan van) OR (luan van)). thoi huyen truc lap".
• Adding a wildcard symbol may retrieve word variants: ((nhung thoi) or (nhung gi)) ((quan van) OR (luan van)). thoi huyen truc lap*.
