• Performing a fuzzy search may retrieve terms with similar spellings: (( thu sach cha me gioi co thong minh ) or ( thu sach ((xa van) OR (ma van)) giai van hoang minh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach cha me gioi co thong minh ) OR ( thu sach ((xa van) OR (ma van)) giai van hoang minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach cha me gioi co thong minh ) or ( thu sach ((xa van) OR (ma van)) giai van hoang minh ))".
• Adding a wildcard symbol may retrieve word variants: (( thu sach cha me gioi co thong minh ) or ( thu sach ((xa van) OR (ma van)) giai van hoang minh ))*.
