Perhaps you should try some spelling variations:
during crisis » during crises, housing crisis
crisis yang » crisis kang, crisis bank, crisis can
can lost » can cost, can lose, can post
von cash » can cash, do cash, von cand
von carl » von karl
yang shu » cong shu, tan shu, yang du
ban yi » ban zi, tan yi
ban ji » ban zi, pan ji, san ji

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 ((ban yi) OR (ban ji)) ((can lost) OR (((von cash) OR (von carl)))) during crisis yang shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((ban yi) OR (ban ji)) ((can lost) or (((von cash) or (von carl)))) during crisis yang shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((ban yi) OR (ban ji)) ((can lost) or (((von cash) or (von carl)))) during crisis yang shu ;*.
