• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((nang ma) or (nang cao)) hoa. hieu van nam ((xuc ban) OR (duc ban)) banh vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((nang ma) OR (nang cao)) hoa. hieu van nam ((xuc ban) OR (duc ban)) banh vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((nang ma) or (nang cao)) hoa. hieu van nam ((xuc ban) OR (duc ban)) banh vai cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((nang ma) or (nang cao)) hoa. hieu van nam ((xuc ban) OR (duc ban)) banh vai cua triet*.
