Perhaps you should try some spelling variations:
how slower » has slower, how slow, low lower
phang der » anhang der, gang der, zwang der
klang der » klarung der, gang der
rent sang » rent sharing
sang minh » kang minah, anh minh, song min
how some » how women
wang » wing, wan, lang

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: wang yan ((phang der) OR (klang der)) rent sang minh ((how some) OR (how slower)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan ((phang der) or (klang der)) rent sang minh ((how some) or (how slower)) ;*.
