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