Let’s dive into the prerequisites before configuring your search network with .NET!

Prerequisites

Before you begin, ensure you have the following:

Required Libraries and Versions:

  • GroupDocs.Search: Ensure compatibility with your environment.
  • GroupDocs.Redaction: Install this library for secure document processing capabilities.

Environment Setup Requirements:

  • .NET Core or .NET Framework installed on your machine.
  • A suitable IDE like Visual Studio.

Knowledge Prerequisites:

  • Basic understanding of C# programming and .NET project setup.
  • Familiarity with search networks and indexing concepts is beneficial.

Setting Up GroupDocs.Redaction for .NET

To get started, set up GroupDocs.Redaction in your .NET environment. Here’s how:

.NET CLI:

dotnet add package GroupDocs.Redaction

Package Manager:

Install-Package GroupDocs.Redaction

NuGet Package Manager UI: Search for “GroupDocs.Redaction” and install the latest version.

License Acquisition:

  • Free Trial: Download a trial license to test GroupDocs.Redaction features.
  • Temporary License: Apply for a temporary license if you need extended access.
  • Purchase: Purchase a full license for long-term usage.

Basic Initialization:

Initialize GroupDocs.Redaction by including it in your project and setting up the configuration as shown below:

using GroupDocs.Redaction;

// Initialize Redactor with a document path
Redactor redactor = new Redactor("sample.pdf");

Implementation Guide

Now, let’s break down each feature into manageable steps.

Configuring Search Network

Overview:

Setting up your search network is the first step to managing large-scale document searches efficiently.

Step 1: Configure Base Path and Port Define the base path for your documents and set a port number. Ensure the port isn’t occupied by another application.

string basePath = \@"YOUR_DOCUMENT_DIRECTORY/AdvancedUsage/Scaling/GettingDocumentsInNetwork/";
int basePort = 49108; // Change if necessary
Configuration configuration = ConfiguringSearchNetwork.Configure(basePath, basePort);

Step 2: Understanding Configuration The Configure method initializes the network with your specified path and port.

Deploying Search Network Nodes

Overview:

Deploy nodes to distribute indexing tasks across multiple servers or instances.

Step 1: Deploy Nodes Use the provided configuration to deploy nodes effectively.

SearchNetworkNode[] nodes = SearchNetworkDeployment.Deploy(basePath, basePort, configuration);
SearchNetworkNode masterNode = nodes[0]; // The first node is considered the master node.

Step 2: Master Node Identification The master node manages network-wide configurations and settings.

Subscribing to Node Events

Overview:

Monitor events on your search network nodes for better management and debugging.

SearchNetworkNodeEvents.Subscibe(masterNode);

Purpose: This method listens to various node activities, ensuring you’re informed about significant changes or issues.

Adding Directories for Indexing

Overview:

Index documents by adding directories containing them into your search network.

string documentsPath = \@"YOUR_DOCUMENT_DIRECTORY/Documents/";
IndexingDocuments.AddDirectories(masterNode, documentsPath);

Key Configuration Options: Ensure the path is correct and accessible from the node to avoid errors during indexing.

Getting Indexed Documents

Overview:

Retrieve information about indexed documents for verification and further processing.

Searcher searcher = masterNode.Searcher;
Indexer indexer = masterNode.Indexer;

int[] shardIndices = masterNode.GetShardIndices();
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];
        Console.WriteLine($"{node.GetNodeIndex(info.ShardIndex)}: {info.ShardIndex}: {info.DocumentInfo.FilePath}");
        
        string[] attributes = indexer.GetAttributes(info.DocumentInfo.FilePath);
        foreach (string attribute in attributes) {
            Console.WriteLine($"\\t\\t{attribute}");
        }
        
        NetworkDocumentInfo[] items = searcher.GetIndexedDocumentItems(info);
        foreach (NetworkDocumentInfo item in items) {
            Console.WriteLine($"\\t{node.GetNodeIndex(item.ShardIndex)}: {item.ShardIndex}: {item.DocumentInfo.ToString()}");
        }
    }
}

Explanation: This section retrieves and prints details of indexed documents, helping you verify the indexing process.

Practical Applications
