Subject useColdSearcher in SolrCloud config
Date Fri, 22 Nov 2013 09:44:28 GMT

The definition of useColdSearcher config element in solrconfig.xml is

"If a search request comes in and there is no current registered searcher,
then immediately register the still warming searcher and use it.  If "false"
then all requests will block until the first searcher is done warming".

By the term 'block', I assume SOLR returns a non 200 response to requests.
Does anybody know the exact response code returned when the server is
blocking requests?

If a new SOLR server is introduced into an existing array of SOLR servers
(in SOLR Cloud setup), it will sync it's index from the leader. To save you
having to specify warm-up queries in the solrconfig.xml file for first
searchers, would/could the new server not auto warm it's caches from the
caches of an existing server?
