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