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