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