• Performing a fuzzy search may retrieve terms with similar spellings: toc sach y ((((nang xa) OR (mang xa))) or (lang xa)) hoi. hieu van cham xuc va danh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach y ((((nang xa) OR (mang xa))) OR (lang xa)) hoi. hieu van cham xuc va danh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach y ((((nang xa) OR (mang xa))) or (lang xa)) hoi. hieu van cham xuc va danh vai cua tre*".
