Solr searcher warming
<p>I was reading the book Solr In Action and am a bit confused about warming searchers . It was mentioned that</p>
<blockquote>
<p>Solr allows for stale reads if a commit is in progress and the current searcher will not be closed until the new searcher has warmed up .</p>
</blockquote>
<p>But a few statements later , it explains about useColdSearcher</p>
<blockquote>
<p>useColdSearcher = false means All actions to solr will be blocked until all the warm up queries have completed</p>
<p>useColdSearcher = true means the new searcher is put into effect well before the warming queries have finished execution .</p>
</blockquote>
<p>I am confused about the current searcher, what happens to that if <code>useColdSearcher=true/false</code>. Does this boolean value have any effect on the closing of current searcher.</p>
