• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thu nang xa hoi. ((hieu va) or (hieu van)) cam xuc va danh vai ((cuu tre) OR (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu nang xa hoi. ((hieu va) OR (hieu van)) cam xuc va danh vai ((cuu tre) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu nang xa hoi. ((hieu va) or (hieu van)) cam xuc va danh vai ((cuu tre) OR (cau treo))*".
