is opened or not?

The setting to use a cold searcher applies whenever a new searcher is 
opened.  It determines what happens while the new searcher is warming. 
If it's false, queries will be answered by the old searcher until all of 
the warming work is complete on the new searcher, at which time Solr 
will switch to the new one and work on dismantling the old one.  If it's 
true, then the new searcher will be used immediately, before warming is 
finished.

In order for Solr to do queries on an index that has changed for any 
reason, including replication, a new searcher is required.  If Solr 
doesn't open a new searcher, it will still be querying the index that 
existed before the change.

Thanks,
Shawn
