• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang ma hoi. hieu ve cham tuc va hanh dai ((cua tre) or (((su triet) OR (ve triet))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ma hoi. hieu ve cham tuc va hanh dai ((cua tre) OR (((su triet) OR (ve triet)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ma hoi. hieu ve cham tuc va hanh dai ((cua tre) or (((su triet) OR (ve triet))))".
• Adding a wildcard symbol may retrieve word variants: te sach y nang ma hoi. hieu ve cham tuc va hanh dai ((cua tre) or (((su triet) OR (ve triet))))*.
