• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((thien danh) or (thien anh)) - hanh tang luat trong cong tac ((han tap) OR (toan tap))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thien danh) OR (thien anh)) - hanh tang luat trong cong tac ((han tap) OR (toan tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thien danh) or (thien anh)) - hanh tang luat trong cong tac ((han tap) OR (toan tap))*".
