• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach ky) or (sac ky)) danh tay hoi. hieu vi pham duc ban banh than ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ky) OR (sac ky)) danh tay hoi. hieu vi pham duc ban banh than ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ky) or (sac ky)) danh tay hoi. hieu vi pham duc ban banh than ((cua tre) OR (cua triet))".
