• Performing a fuzzy search may retrieve terms with similar spellings: toc sach tu ((nang xa) OR (lang xa)) hoi. hieu qua ca xuc va dang ((dieu cu) or (dieu cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach tu ((nang xa) OR (lang xa)) hoi. hieu qua ca xuc va dang ((dieu cu) OR (dieu cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach tu ((nang xa) OR (lang xa)) hoi. hieu qua ca xuc va dang ((dieu cu) or (dieu cua)) te*".
