Perhaps you should try some spelling variations:
using chart » using charts, using chairs, using smart
cut using » out using, att using, et using
roberto n » robert _, robert e, robert a
tan yang » dan yang, tan ying, tao yang
tan yong » tan kong, tan ying, wang yong
time cut » time count, time cost
robert j » robert _, robert e
ii time » iii time, ii theme

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 (tan yong))) OR (tan hong)) ii time cut using chart ((roberto n) OR (robert j)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((tan yang) or (tan yong))) or (tan hong)) ii time cut using chart ((roberto n) OR (robert j)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((((tan yang) or (tan yong))) or (tan hong)) ii time cut using chart ((roberto n) OR (robert j)) ;*.
