• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sang)) - hanh thong qua ((dung cong) OR (dung trong)) van than cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sang)) - hanh thong qua ((dung cong) or (dung trong)) van than cao".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sang)) - hanh thong qua ((dung cong) or (dung trong)) van than cao*.
