• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty ((hang tai) or (hang va)) hoi. lieu va cam duc ((va danh) OR (va dan)) tien cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((hang tai) OR (hang va)) hoi. lieu va cam duc ((va danh) OR (va dan)) tien cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((hang tai) or (hang va)) hoi. lieu va cam duc ((va danh) OR (va dan)) tien cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((hang tai) or (hang va)) hoi. lieu va cam duc ((va danh) OR (va dan)) tien cua triet*.
