• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky dang xa hoi. thien ((van cham) OR (van tham)) loc ((va danh) or (va dan)) vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky dang xa hoi. thien ((van cham) OR (van tham)) loc ((va danh) OR (va dan)) vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky dang xa hoi. thien ((van cham) OR (van tham)) loc ((va danh) or (va dan)) vai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky dang xa hoi. thien ((van cham) OR (van tham)) loc ((va danh) or (va dan)) vai cua tre*.
