Perhaps you should try some spelling variations:
costs during » courts during, roosts during, cats during
during risk » using risk, during crises, during crisis
land costs » land cost, wind costs, aid costs
yang kong » king kong, tan kong, yang yang
how scale » how stable, how small, how space
how some » how women
hong » long

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 ((yang kong) OR (hong kong)) land costs during risk ((how some) OR (how scale)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang kong) OR (hong kong)) land costs during risk ((how some) or (how scale)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang kong) OR (hong kong)) land costs during risk ((how some) or (how scale)) ;*.
