• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu tinh - thanh trung cua thong ((((tuong tap) OR (tuong tac))) or (luong tap)) toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - thanh trung cua thong ((((tuong tap) OR (tuong tac))) OR (luong tap)) toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - thanh trung cua thong ((((tuong tap) OR (tuong tac))) or (luong tap)) toan cau*".
