• Performing a fuzzy search may retrieve terms with similar spellings: so sach v nang ((doc hoi) OR (doc hai)). thien van bac xuc van nhanh hai ((chu tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach v nang ((doc hoi) OR (doc hai)). thien van bac xuc van nhanh hai ((chu tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach v nang ((doc hoi) OR (doc hai)). thien van bac xuc van nhanh hai ((chu tre) or (cuu tre))*".
