• If you are trying to use Boolean operators, they must be ALL CAPS: (((("thu sach dao cho nguoi") OR ("thu lanh dao cho nguoi"))) OR ("thu hoach dat lam nguoi")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"thu sach dao cho nguoi\") OR (\"thu lanh dao cho nguoi\"))) or (\"thu hoach dat lam nguoi\"))".
• Removing quotes may allow a broader search: (((( thu sach dao cho nguoi ) OR ( thu lanh dao cho nguoi ))) or ( thu hoach dat lam nguoi )).
