• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((y lang) OR (tay lang)) ha hoi. hieu ve ((cham tuc) or (pham thuc)) ban thanh le cua vat~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y lang) OR (tay lang)) ha hoi. hieu ve ((cham tuc) OR (pham thuc)) ban thanh le cua vat*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y lang) OR (tay lang)) ha hoi. hieu ve ((cham tuc) or (pham thuc)) ban thanh le cua vat*".
