• Performing a fuzzy search may retrieve terms with similar spellings: te sach kho ((tang xa) OR (tang ma)) hoi. hieu van ((cac duc) or (cac dac)) ban thanh ha cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach kho ((tang xa) OR (tang ma)) hoi. hieu van ((cac duc) OR (cac dac)) ban thanh ha cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach kho ((tang xa) OR (tang ma)) hoi. hieu van ((cac duc) or (cac dac)) ban thanh ha cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach kho ((tang xa) OR (tang ma)) hoi. hieu van ((cac duc) or (cac dac)) ban thanh ha cua triet*.
