Getting documents in network Leave feedback
To obtain a list of indexed documents in a specific search network shard, call the GetIndexedDocuments method of the Searcher class. The method returns an array of NetworkDocumentInfo objects; each of them contains the information about the document (DocumentInfo property) and the index of the shard that contains it (ShardIndex property).
To obtain a list of shards of the search network, use the GetShardIndices method of the SearchNetworkNode class. To get the index of the node on which a shard is located, use the GetNodeIndex method.
It is also possible to get a list of nested items of an indexed container document. To do this, use the GetIndexedDocumentItems method of the Searcher class.
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 obtaining a list of documents indexed in the search network, as well as outputting the resulting data and the attributes of the documents to the console.
C#
Searcher searcher = node.Searcher;
Indexer indexer = node.Indexer;
int[] shardIndices = node.GetShardIndices();
Console.WriteLine();
for (int i = 0; i < shardIndices.Length; i++)
{
int shardIndex = shardIndices[i];
NetworkDocumentInfo[] infos = searcher.GetIndexedDocuments(shardIndex);
for (int j = 0; j < infos.Length; j++)
{
NetworkDocumentInfo info = infos[j];
int nodeIndex = node.GetNodeIndex(info.ShardIndex);
Console.WriteLine(nodeIndex + ": " + info.ShardIndex + ": " + info.DocumentInfo.FilePath);
string[] attributes = indexer.GetAttributes(info.DocumentInfo.FilePath);
for (int k = 0; k < attributes.Length; k++)
{
Console.WriteLine("\t\t" + attributes[k]);
}
NetworkDocumentInfo[] items = searcher.GetIndexedDocumentItems(info);
for (int k = 0; k < items.Length; k++)
{
NetworkDocumentInfo item = items[k];
Console.WriteLine("\t" + nodeIndex + ": " + item.ShardIndex + ": " + item.DocumentInfo.ToString());
}
}
}
