• Performing a fuzzy search may retrieve terms with similar spellings: (((("te sach hoi lam nguoi") OR ("te sach hoi tay nguoi"))) or ("tu sach hoc tap nguoi"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("te sach hoi lam nguoi") OR ("te sach hoi tay nguoi"))) OR ("tu sach hoc tap nguoi"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"te sach hoi lam nguoi\") OR (\"te sach hoi tay nguoi\"))) or (\"tu sach hoc tap nguoi\"))*".
• Removing quotes may allow a broader search: (((( te sach hoi lam nguoi ) OR ( te sach hoi tay nguoi ))) or ( tu sach hoc tap nguoi ))*.
