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