• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((v nang) OR (vu nang)) ma hoi. hieu ((van thanh) or (ban thanh)) luc van anh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((v nang) OR (vu nang)) ma hoi. hieu ((van thanh) OR (ban thanh)) luc van anh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((v nang) OR (vu nang)) ma hoi. hieu ((van thanh) or (ban thanh)) luc van anh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ((v nang) OR (vu nang)) ma hoi. hieu ((van thanh) or (ban thanh)) luc van anh vai cua tre*.
