Perhaps you should try some spelling variations:
change roberto » chang roberto, change robert, echandi roberto
thing change » things change, using change, teaching change
roberto bola » roberto bolano, roberto rocha, robert bos2
time last » time list, time past, time class
time lost » time cost, time loss, time list
tan yang » dan yang, tan ying, tan yong
yang yi » yang di, yang xi, yang jui

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: tan yang yi ((time last) OR (time lost)) thing change roberto bola ;~.
• Adding a wildcard symbol may retrieve word variants: tan yang yi ((time last) or (time lost)) thing change roberto bola ;*.
