• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thien hach - hanh ((trinh cua) OR (trinh luat)) ((nhung huong) OR (nhung cong)) dan than ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thien hach - hanh ((trinh cua) OR (trinh luat)) ((nhung huong) or (nhung cong)) dan than ban".
