• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) OR (thuat sach)) tu ((nang xa) or (lang xa)) hoi. hieu ve cam suc manh hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (thuat sach)) tu ((nang xa) OR (lang xa)) hoi. hieu ve cam suc manh hanh vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) OR (thuat sach)) tu ((nang xa) or (lang xa)) hoi. hieu ve cam suc manh hanh vai cuu tre".
