• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach ky) OR (sac ky)) nang ma hoi. hieu van cau luc ban anh di ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ky) OR (sac ky)) nang ma hoi. hieu van cau luc ban anh di ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ky) OR (sac ky)) nang ma hoi. hieu van cau luc ban anh di ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ky) OR (sac ky)) nang ma hoi. hieu van cau luc ban anh di ((cua tre) or (cua te))*.
