• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach danh) or (sach dao)) ((((((hoa khi) OR (hoc khi))) or (hoa hi))) or (hoa phi)) đong luc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach danh) OR (sach dao)) ((((((hoa khi) OR (hoc khi))) OR (hoa hi))) OR (hoa phi)) đong luc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach danh) or (sach dao)) ((((((hoa khi) OR (hoc khi))) or (hoa hi))) or (hoa phi)) đong luc".
• Adding a wildcard symbol may retrieve word variants: tu ((sach danh) or (sach dao)) ((((((hoa khi) OR (hoc khi))) or (hoa hi))) or (hoa phi)) đong luc*.
