• Performing a fuzzy search may retrieve terms with similar spellings: tu ((((sach tu) OR (sach thu))) or (sach ty)) ang xa hoi. hieu van nam tuc xa hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((((sach tu) OR (sach thu))) OR (sach ty)) ang xa hoi. hieu van nam tuc xa hanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((((sach tu) OR (sach thu))) or (sach ty)) ang xa hoi. hieu van nam tuc xa hanh vai cua tre*".
