• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((thu nang) OR (thu bang)) x hoi. hieu ve ((cac nuoc) or (cap nuoc)) ban hang vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((thu nang) OR (thu bang)) x hoi. hieu ve ((cac nuoc) OR (cap nuoc)) ban hang vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((thu nang) OR (thu bang)) x hoi. hieu ve ((cac nuoc) or (cap nuoc)) ban hang vai cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach ((thu nang) OR (thu bang)) x hoi. hieu ve ((cac nuoc) or (cap nuoc)) ban hang vai cua triet*.
