• Performing a fuzzy search may retrieve terms with similar spellings: hoc chau tinh - hanh trinh ((((luat tong) OR (luat thong))) or (luat trong)) cong dan toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chau tinh - hanh trinh ((((luat tong) OR (luat thong))) OR (luat trong)) cong dan toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chau tinh - hanh trinh ((((luat tong) OR (luat thong))) or (luat trong)) cong dan toan ban*".
