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