how to remove objects cached in data cache?

With following query, I can find out how the  table cached in data cache with the indexes: 

Select CacheName,DBName,OwnerName,ObjectName,IndexID,sum(CachedKB) as "CachedKb"

from master..monCachedObject

where ObjectName = 'invent'

group by CacheName,DBName,OwnerName,ObjectName,IndexID

order by CacheName,DBName,OwnerName,ObjectName,IndexID

Is it possible to remove the cached data for particular index from data cache? I want to verify the performance issue is on particular index and reproduce the performance issue.
