License Acquisition

  • Free Trial: Start by obtaining a free trial license to explore the full capabilities of GroupDocs.Search.
  • Temporary License: If needed, request a temporary license for extended evaluation.
  • Purchase: For long-term use, consider purchasing a commercial license.

Basic Initialization and Setup

import com.groupdocs.search.Configuration;
// Initialize configuration with your document path and port
String basePath = "YOUR_DOCUMENT_DIRECTORY/AdvancedUsage/Scaling/GettingDocumentsInNetwork/";
int basePort = 49112;

Configuration config = new Configuration(basePath, basePort);

Implementation Guide

Let’s break down the implementation into feature-specific sections to better understand how each component works.

Configuring Search Network

Overview: This section demonstrates setting up a search network using GroupDocs.Search, allowing you to manage document indexing and searching efficiently.

Step 1: Import Required Packages

import com.groupdocs.search.scaling.ConfiguringSearchNetwork;
import com.groupdocs.search.scaling.Configuration;

Step 2: Configure the Network

Specify the base path and port for your search network configuration.

String basePath = "YOUR_DOCUMENT_DIRECTORY/AdvancedUsage/Scaling/GettingDocumentsInNetwork/";
int basePort = 49112;

Configuration configuration = ConfiguringSearchNetwork.configure(basePath, basePort);
  • Parameters: basePath is where your documents reside. basePort serves as the network communication port.

Deploying Search Network Nodes

Overview: This feature guides you through deploying nodes in a search network to distribute indexing tasks efficiently across multiple machines or environments.

Step 1: Import Deployment Package

import com.groupdocs.search.scaling.SearchNetworkDeployment;
import com.groupdocs.search.scaling.SearchNetworkNode;

Step 2: Deploy Nodes

Deploy your nodes using the configured settings.

String[] nodes = SearchNetworkDeployment.deploy(basePath, basePort, configuration);
SearchNetworkNode masterNode = nodes[0]; // Designate the first node as the master node
  • Master Node: The masterNode acts as a central point for coordinating searches and indexing tasks.

Subscribing to Node Events

Overview: Learn how to subscribe to events on a search network node, enabling real-time updates and responses within your application.

Step 1: Import Event Package

import com.groupdocs.search.scaling.SearchNetworkNodeEvents;

Step 2: Subscribe to Master Node Events

Connect event handlers for the master node.

SearchNetworkNodeEvents.subscribe(masterNode);
  • Event Handling: This setup allows your application to react dynamically as indexing or search operations occur.

Adding Directories for Indexing

Overview: Efficiently add directories of documents to be indexed by the GroupDocs.Search indexer, ensuring comprehensive document coverage.

Step 1: Import Indexer Package

import com.groupdocs.search.examples.Utils;
import com.groupdocs.search.scaling.Indexer;

Step 2: Add Document Directories

Incorporate your desired directories for indexing.

Indexer indexer = masterNode.getIndexer();
indexer.addDirectories("YOUR_DOCUMENT_DIRECTORY/DocumentsPath");
  • Dynamic Indexing: By adding multiple directories, you can ensure that all relevant documents are indexed.

Retrieving Indexed Documents

Overview: Access and retrieve information about the indexed documents to verify indexing results or perform searches.

Step 1: Import Searcher Package

import com.groupdocs.search.scaling.Searcher;
import com.groupdocs.search.scaling.NetworkDocumentInfo;

Step 2: Retrieve Document Information

Loop through shards to access document data.

Searcher searcher = masterNode.getSearcher();
int[] shardIndices = masterNode.getShardIndices();

for (int i = 0; i < shardIndices.length; i++) {
    int shardIndex = shardIndices[i];
    NetworkDocumentInfo[] infos = searcher.getIndexedDocuments(shardIndex);

    for (NetworkDocumentInfo info : infos) {
        int nodeIndex = masterNode.getNodeIndex(info.getShardIndex());
        String filePath = info.getDocumentInfo().getFilePath();

        // Retrieve and process document attributes
        String[] attributes = indexer.getAttributes(filePath);
        
        NetworkDocumentInfo[] items = searcher.getIndexedDocumentItems(info);
        for (NetworkDocumentInfo item : items) {
            // Process each indexed item
        }
    }
}
  • Shard Management: Utilize shard indices to efficiently manage and retrieve document data across distributed nodes.

Practical Applications

GroupDocs.Search offers versatile use cases:

  1. Enterprise Document Management: Streamline document retrieval for large corporations with extensive archives.
  2. Legal Firms: Enhance case file searches, improving efficiency in research tasks.
  3. Academic Research: Facilitate literature reviews by quickly locating relevant academic papers.

Performance Considerations

To maximize performance when using GroupDocs.Search:

  • Optimize Indexing: Regularly update your index and remove obsolete data to keep it lean and efficient.
  • Memory Management: Monitor Java memory usage, especially in large-scale deployments, to prevent bottlenecks.
  • Scalability: Design your search network with scalability in mind, allowing for additional nodes as your document corpus grows.

Conclusion

You’ve now mastered the essentials of configuring and deploying a GroupDocs.Search network using Java. With this knowledge, you’re well-equipped to implement robust document management solutions tailored to your specific needs.
