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