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