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