• Performing a fuzzy search may retrieve terms with similar spellings: te cac ky ((nang xa) OR (nang ma)) hoi. hieu ((van thai) or (va tham)) son va hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te cac ky ((nang xa) OR (nang ma)) hoi. hieu ((van thai) OR (va tham)) son va hanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cac ky ((nang xa) OR (nang ma)) hoi. hieu ((van thai) or (va tham)) son va hanh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: te cac ky ((nang xa) OR (nang ma)) hoi. hieu ((van thai) or (va tham)) son va hanh vi cua triet*.
