fix debug print statements
fix hanging when doing &stream=1 for
a federated search. hack it so it
thinks we got m_msg3a.m_numDocIds summaries
after we've printed what was requested.
so we don't waste time getting all the summaries.
this popped up for federated search because
we merged the msg3as into a single msg3a and had
an overabundance of docids.
