• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu tinh - hanh tang cua thuong ((cong dan) OR (cong tan)) ((toan tai) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu tinh - hanh tang cua thuong ((cong dan) or (cong tan)) ((toan tai) or (toan cao))*.
