• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) OR (vu sach)) thue nang xa hoi. hieu ve cam duc va danh ((vai cua) or (lai cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) thue nang xa hoi. hieu ve cam duc va danh ((vai cua) OR (lai cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) thue nang xa hoi. hieu ve cam duc va danh ((vai cua) or (lai cua)) triet".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (vu sach)) thue nang xa hoi. hieu ve cam duc va danh ((vai cua) or (lai cua)) triet*.
