Perhaps you should try some spelling variations:
thing change » things change, teaching change, getting change
using change » using exchange, putting change, sensing change
time lasten » time listen, die lasten, time latent
robert bin » robert b, robert n, robert i
time last » time list, time past, time lost
tan yang » dan yang, tan ying, tan yong

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 di ((time last) OR (time lasten)) ((thing change) OR (using change)) robert bin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tan yang di ((time last) or (time lasten)) ((thing change) OR (using change)) robert bin ;~".
• Adding a wildcard symbol may retrieve word variants: tan yang di ((time last) or (time lasten)) ((thing change) OR (using change)) robert bin ;*.
