How do I extend the Timeout in SolrConnection? (SolrConnectionException: The operation has timed out)

How do I extend/modify the timeout value used for the SolrConnection object?

I have a long-running optimize operation that does not appear to complete within the default connection timeout provided. The operation I am using is ISolrOperations<?>.Optimize(). I do not see any options for increasing the timeout using the ISolrOperations object directly.

I am using the Castle Windsor IoC container for instantiation in order to have multiple cores.

Here is the full stacktrace:

SolrNet.Exceptions.SolrConnectionException: The operation has timed out ---> System.Net.WebException: The operation has timed out
   at System.Net.HttpWebRequest.GetResponse()
   at HttpWebAdapters.Adapters.HttpWebRequestAdapter.GetResponse() in c:\prg\SolrNet\svn\HttpWebAdapters\Impl\HttpWebRequestAdapter.cs:line 36

   at SolrNet.Impl.SolrServer`1.Optimize() in c:\prg\SolrNet\svn\SolrNet\Impl\SolrServer.cs:line 206
   at NationalLaborRelations.SearchAgent.SearchAgentBase.Optimize(ISolrOperations`1 s) in C:\PROJECTS\NLRB\Search\SearchAgent\SearchAgent\SearchAgentBase.cs:line 354

Note that the optimization does happen successfully, but that SolrNet does not wait for it to complete before throwing this error.

You can safely ignore this timeout. As you already have found out, the command runs successfully on Solr anyway.

Or if you want to set the connection timeout you can configure it with a component model event in Windsor:

var c = new WindsorContainer();
c.Kernel.ComponentModelCreated += model => {
    if (model.Implementation == typeof(SolrConnection))
        model.Parameters.Add("Timeout", "200000");
};
c.AddFacility("solr", new SolrNetFacility("http://localhost:8983/solr")); // or whatever

Timeout value is expressed in milliseconds.
