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