Perhaps you should try some spelling variations:
juan rene » juan meng, juan rana
rene than » rene ten
using v2 » using avd, using vba, using vhr
than bad » than bau, than a, than big
using v » using _, using a, using 1
long yu » hong yu, long du, long run
rong yu » hong yu, rong su, wong yue

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: done ((using v) OR (using v2)) juan rene than bad ((long yu) OR (rong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "done ((using v) or (using v2)) juan rene than bad ((long yu) OR (rong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: done ((using v) or (using v2)) juan rene than bad ((long yu) OR (rong yu)) ;*.
