• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky dong hoa hoi. lieu va ((((tham soc) OR (cham soc))) or (thai son)) va thanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky dong hoa hoi. lieu va ((((tham soc) OR (cham soc))) OR (thai son)) va thanh vi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky dong hoa hoi. lieu va ((((tham soc) OR (cham soc))) or (thai son)) va thanh vi cuu tre*".
