• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((nham nang) OR (kha nang)) ma hoi. hieu ((ve cam) or (ve cac)) duc ban thanh le cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((nham nang) OR (kha nang)) ma hoi. hieu ((ve cam) OR (ve cac)) duc ban thanh le cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((nham nang) OR (kha nang)) ma hoi. hieu ((ve cam) or (ve cac)) duc ban thanh le cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach ((nham nang) OR (kha nang)) ma hoi. hieu ((ve cam) or (ve cac)) duc ban thanh le cua triet*.
