Perhaps you should try some spelling variations:
know than » know what, know them, know when
yang yang » wang yang, wang yan
yang jin » yang jie, yang jun, ying jin
yang xi » yang yi, yang jui
18 may » 11 may, 19 may, 10 may
c bank » 1 bank, c band, e bank
bank a » bank _, bank adb
a know » a known, _ know, i know
nr 18 » nr 1, nr 12, nr 14
may c » may _, ray c, may 2

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: ((((yang xi) OR (((yang jin) OR (yang yang))))) OR (yang di))nr 18 may c bank a know than ;~.
• Adding a wildcard symbol may retrieve word variants: ((((yang xi) or (((yang jin) or (yang yang))))) or (yang di))nr 18 may c bank a know than ;*.
