Perhaps you should try some spelling variations:
machine aids » machine minds, machine ages, machine arts
going green » growing green, being green, using green
ai machine » a machine, 4 machine, 2 machine
green ai » green a, green bim, green gap
yang jui » yang di, yang xi
yang yi » yang di, yang xi
judy » july
wang » wing, lang

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: going green ai machine aids ((((yang jui) OR (yang yi))) OR (yang judy)) (wang OR wan) hua ;~.
• Adding a wildcard symbol may retrieve word variants: going green ai machine aids ((((yang jui) or (yang yi))) or (yang judy)) (wang or wan) hua ;*.
