• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chuc) OR (hoc chuc)) nang - anh nang quan hanh cong san ((than tap) OR (han tap)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chuc) OR (hoc chuc)) nang - anh nang quan hanh cong san ((than tap) or (han tap))".
• Adding a wildcard symbol may retrieve word variants: ((ho chuc) OR (hoc chuc)) nang - anh nang quan hanh cong san ((than tap) or (han tap))*.
