• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (hoc thieu)) sang - hanh tang luan ((thuong thong) OR (thong phuong)) tan toan cao~.
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) or (hoc thieu)) sang - hanh tang luan ((thuong thong) or (thong phuong)) tan toan cao*.
