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