Perhaps you should try some spelling variations:
chang roberto » chase robert
time lasten » time listen, die lasten, time latent
using chang » using change, using chart, ying chang
roberto bin » roberto n, roberto bola, roberto luis
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)) using chang roberto bin ;~.
• Adding a wildcard symbol may retrieve word variants: tan yang di ((time last) or (time lasten)) using chang roberto bin ;*.
