• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) OR (toc sach)) ky ((nang ma) or (lang xa)) hoi. hieu ve cam xuc ban thanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) ky ((nang ma) OR (lang xa)) hoi. hieu ve cam xuc ban thanh vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) ky ((nang ma) or (lang xa)) hoi. hieu ve cam xuc ban thanh vi cua tre*".
