• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((chieu tinh) OR (chau tinh))) OR (ha tinh)) - hanh trung ha cong phuong anh toan cau~.
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu tinh) or (chau tinh))) or (ha tinh)) - hanh trung ha cong phuong anh toan cau*.
