• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) OR (sac ky)) ((nang xa) or (nang ma)) hoi. lieu va cam thuc va danh di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sac ky)) ((nang xa) OR (nang ma)) hoi. lieu va cam thuc va danh di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sac ky)) ((nang xa) or (nang ma)) hoi. lieu va cam thuc va danh di cua tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sac ky)) ((nang xa) or (nang ma)) hoi. lieu va cam thuc va danh di cua tre*.
