• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (toc sach)) ky dang van hoa. lieu va lam truoc ((va hanh) OR (va danh)) tai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (toc sach)) ky dang van hoa. lieu va lam truoc ((va hanh) OR (va danh)) tai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (toc sach)) ky dang van hoa. lieu va lam truoc ((va hanh) OR (va danh)) tai cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (toc sach)) ky dang van hoa. lieu va lam truoc ((va hanh) OR (va danh)) tai cuu tre*.
