• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((chieu xanh) OR (chieu sang))) OR (lieu tinh)) - hanh tranh cua thuong cong tinh toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu xanh) OR (chieu sang))) or (lieu tinh)) - hanh tranh cua thuong cong tinh toan cao~".
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu xanh) OR (chieu sang))) or (lieu tinh)) - hanh tranh cua thuong cong tinh toan cao*.
