• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - hanh ((((trinh cua) OR (tinh cua))) OR (trinh han)) nhung cong van thanh tai~.
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - hanh ((((trinh cua) or (tinh cua))) or (trinh han)) nhung cong van thanh tai*.
