numDocs methods seem just for filterCache. So I just need use QueryResult 
search(QueryResult qr, QueryCommand cmd) by setting QueryCommand.len=0?I would 
try it.

In my app,I want to search numdocs for some queries. I see SolrIndexSearcher 
has two methods:
public int numDocs(Query a, DocSet b)
public int numDocs(Query a, Query b)

But these're not fit for me.For search's params,I get q and fq, and q' results 
are not in filterCache.But above methods are both using filtercache. So I think 
a method like:
public int numDocs(Query q, List<Query> fqs) (q not with filtercache,fqs with 
filtercache)
would be fine.
And now,I cannot extend SolrIndexSearcher because of SolrCore. What should I do 
to solve the problem?
thanks.
