• Performing a fuzzy search may retrieve terms with similar spellings: toc sach y lang ha hoi. thi van cau xuc ((va hanh) or (va danh)) trinh ((luat tu) OR (luat tuc))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach y lang ha hoi. thi van cau xuc ((va hanh) OR (va danh)) trinh ((luat tu) OR (luat tuc)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach y lang ha hoi. thi van cau xuc ((va hanh) or (va danh)) trinh ((luat tu) OR (luat tuc))".
• Adding a wildcard symbol may retrieve word variants: toc sach y lang ha hoi. thi van cau xuc ((va hanh) or (va danh)) trinh ((luat tu) OR (luat tuc))*.
