• Performing a fuzzy search may retrieve terms with similar spellings: hoc bien tinh - hanh tang cua thong ((((thong dan) OR (thong van))) or (thong den)) thai cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc bien tinh - hanh tang cua thong ((((thong dan) OR (thong van))) OR (thong den)) thai cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc bien tinh - hanh tang cua thong ((((thong dan) OR (thong van))) or (thong den)) thai cao*".
