Synchronizing shards Leave feedback

If there is any communication interruption in the search network, some operations may not complete correctly. To resolve such problems, call the Synchronize method of the Indexer class. The method synchronizes the list of indexed documents kept by the indexer with the documents in the shards.

The asynchronous operation flag is available as an option (SynchronizeOptions.IsAsync). You can track the completion of the operation by subscribing to the SynchronizationCompleted event.

The examples on this page use the master node of a running search network. The following code creates and starts the master node as described on the Search network deployment page; the slave nodes must be started beforehand.

C#

string basePath = @"c:\SearchNetwork\";
int basePort = 49100;

// Loading the search network configuration from a file
Configuration configuration = Configuration.Load(basePath + "Configuration.xml");

// Creating, configuring and starting the master node; the timeouts are specified in milliseconds
SearchNetworkNode node = SearchNetworkNode.CreateMasterNode(
    0,
    basePath + "Node0",
    new TcpSettings(basePort, 3000, 3000, 3000, 1000),
    new FileLogger(basePath + "Log.txt", 4.0),
    configuration);
node.ConfigureAllNodes();
node.Start();

The following code example, which continues the previous one, demonstrates how to synchronize search network nodes.

C#

Console.WriteLine("Synchronizing shards");
Indexer indexer = node.Indexer;
SynchronizeOptions options = new SynchronizeOptions();
indexer.Synchronize(options);
