• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky dang xay hoi. lieu va nam ((xuc va) OR (tuc va)) hanh va ((cau treo) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky dang xay hoi. lieu va nam ((xuc va) OR (tuc va)) hanh va ((cau treo) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky dang xay hoi. lieu va nam ((xuc va) OR (tuc va)) hanh va ((cau treo) or (cua triet))".
