  2. Temporary License: Obtain a temporary license to test without evaluation limitations by visiting GroupDocs Temporary License.
  3. Purchase: For long-term use, consider purchasing a license from GroupDocs Purchase Page.

Basic Initialization and Setup

Initialize your project with GroupDocs.Search as follows:

Configuration config = new Configuration();
// Set up basic configuration settings for your application.

This initialization step is crucial to ensure that all components function seamlessly within your search network.

Implementation Guide

Now, let’s break down the process into manageable sections, each focusing on a specific feature of deploying and managing search network nodes.

Feature 1: Configuration Setup

Overview: Setting up the configuration for your search network is the first step in deploying nodes. This setup involves specifying paths and ports critical for node deployment.

Implementation Steps:

Step 1: Define Base Path and Port
String basePath = "/path/to/config";
int basePort = 8080;
Step 2: Configure Search Network

The configureSearchNetwork function prepares the configuration object necessary for deploying nodes.

Configuration config = configureSearchNetwork(basePath, basePort);
  • Parameters: The base path and port are used to locate resources and establish communication channels.
  • Return Value: A configured Configuration object tailored to your deployment needs.

Feature 2: Search Network Deployment

Overview: Deploying nodes is essential for scaling your search capabilities across different environments or segments of data.

Implementation Steps:

Step 1: Deploy Nodes

The deploySearchNetwork function initializes and returns an array of search network nodes.

SearchNetworkNode[] nodes = deploySearchNetwork(basePath, basePort, config);
  • Parameters: Base path, port, and configuration are used to determine the deployment environment.
  • Return Value: An array containing initialized SearchNetworkNodes.

Feature 3: Subscribing to Network Events

Overview: Monitoring your search network’s activities is crucial for maintaining optimal performance and reliability.

Implementation Steps:

Step 1: Subscribe to Master Node Events
subscribeToNodeEvents(nodes[0]); // Assuming the master node is at index 0.
  • Purpose: This step ensures that you are notified of significant events or changes within your search network.

Feature 4: Indexing Documents

Overview: Adding directories containing documents to be indexed allows for efficient data retrieval across your network.

Implementation Steps:

Step 1: Add Directories
addDirectoriesToIndex(nodes[0]); // Use the master node for indexing.
  • Purpose: Facilitates quick access and searchability of all documents within specified directories.

Feature 5: Adding Attributes to Documents

Overview: Custom attributes enhance document metadata, making searches more flexible and informative.

Implementation Steps:

Step 1: Add an Attribute
addAttribute(nodes[0], "documentKey123", "customAttribute");
  • Parameters: Specify the node, document key, and attribute to be added.
  • Purpose: Extends the search functionality by enriching documents with additional metadata.

Feature 6: Retrieving Indexed Documents

Overview: Efficiently retrieve and list indexed documents to ensure data accuracy and completeness.

Implementation Steps:

Step 1: Get Indexed Documents
getIndexedDocuments(nodes[0]);
  • Purpose: Verifies the successful indexing of all necessary documents within your search network.

Feature 7: Closing Network Nodes

Overview: Properly closing nodes is crucial for resource management and preventing memory leaks.

Implementation Steps:

Step 1: Close All Nodes
closeNodes(nodes);
  • Purpose: Releases resources occupied by each node, ensuring a clean shutdown process.

Practical Applications

Here are some real-world use cases where managing search network nodes with GroupDocs.Search for Java can be incredibly beneficial:

  1. Enterprise Document Management: Enhance document retrieval in large organizations by indexing and searching across multiple departments.
  2. E-commerce Platforms: Improve product search capabilities by quickly accessing extensive catalogs stored on different servers.
  3. Legal Firms: Facilitate case research by organizing vast amounts of legal documents into an easily searchable format.
