Perhaps you should try some spelling variations:
when dealing » when scaling, when learning, when facing
when being » women being, when using, when setting
done using » line using, move using
john wong » john song, john bonn
dann bin » dong bin
wong siu » wong shiu, kong siu, wong sau
a tax » _ tax

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((done using) or (dann bin)) a tax ((when being) OR (when dealing)) john wong siu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((done using) OR (dann bin)) a tax ((when being) OR (when dealing)) john wong siu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((done using) or (dann bin)) a tax ((when being) OR (when dealing)) john wong siu ;".
• Adding a wildcard symbol may retrieve word variants: ((done using) or (dann bin)) a tax ((when being) OR (when dealing)) john wong siu ;*.
