• Performing a fuzzy search may retrieve terms with similar spellings: ((ho chieu) OR (theo chieu)) xanh - hanh ((trang van) or (trang va)) dung huong van toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) xanh - hanh ((trang van) OR (trang va)) dung huong van toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) xanh - hanh ((trang van) or (trang va)) dung huong van toan cau".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (theo chieu)) xanh - hanh ((trang van) or (trang va)) dung huong van toan cau*.
