Perhaps you should try some spelling variations:
using phase » using past, closing phase, testing phase
cut using » out using, att using, et using
time cut » time count, time cost
tan yang » dan yang, tan ying, tan yong
robert b » robert _, robert e, robert a
robert j » robert _, robert e
un yang » daun yang, dan yang, hui yang
i time » ii time, 3 time, 4 time

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) OR (un yang)) i time cut using phase ((robert b) OR (robert j)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tan yang) or (un yang)) i time cut using phase ((robert b) OR (robert j)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((tan yang) or (un yang)) i time cut using phase ((robert b) OR (robert j)) ;*.
