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