Implementation Guide

Let’s break down each feature into steps and implementation details.

Configuring Search Network

Overview: This section explains how to set up a search network using specified base paths and ports.

import com.groupdocs.search.dictionaries.*;
import com.groupdocs.search.scaling.configuring.*;

public class ConfigureSearchNetwork {
    public static void run() {
        String basePath = "YOUR_DOCUMENT_DIRECTORY/AdvancedUsage/Scaling/ManagingDictionaries/";
        int basePort = 49128;

        Configuration configuration = ConfiguringSearchNetwork.configure(basePath, basePort);
        
        // Configuration details and setup logic
    }
}
  • Parameters:
    • basePath: Directory path for managing dictionaries.
    • basePort: Port number for network communication.

Deploying Search Network Nodes

Overview: Learn how to deploy nodes in a distributed search network environment.

import com.groupdocs.search.scaling.*;

public class DeploySearchNetworkNodes {
    public static void run() {
        String basePath = "YOUR_DOCUMENT_DIRECTORY/AdvancedUsage/Scaling/ManagingDictionaries/";
        int basePort = 49128;
        Configuration configuration = new Configuration();

        SearchNetworkNode[] nodes = SearchNetworkDeployment.deploy(basePath, basePort, configuration);
        
        // Node deployment logic
    }
}
  • Key Steps:
    • Initialize Configuration.
    • Deploy nodes using the deploy method.

Subscribing to Node Events

Overview: Monitor network events by subscribing an event listener to a master node.

import com.groupdocs.search.scaling.*;

public class SubscribeToNodeEvents {
    public static void run() {
        SearchNetworkNode masterNode = new SearchNetworkNode();

        SearchNetworkNodeEvents.subscribe(masterNode);
        
        // Event subscription logic
    }
}
  • Key Considerations:
    • Ensure the masterNode is properly initialized.
    • Handle events appropriately to maintain network stability.

Adding Synonyms to a Node’s Indexer

Overview: Enhance search relevance by adding synonyms to the indexer’s dictionary.

import com.groupdocs.search.dictionaries.*;
import com.groupdocs.search.scaling.*;

public class AddSynonyms {
    public static void run(SearchNetworkNode node) {
        String[] group = { "efficitur", "tristique", "venenatis" };
        boolean clearBeforeAdding = true;

        Indexer indexer = node.getIndexer();
        int[] indices = node.getShardIndices();
        SynonymDictionary dictionary = indexer.getSynonymDictionary(indices[0]);

        if (clearBeforeAdding) {
            dictionary.clear();
        }
        dictionary.addRange(new String[][] { group });

        indexer.setDictionary(dictionary);
        
        // Synonym addition logic
    }
}
  • Important Parameters:
    • group: Array of synonyms.
    • clearBeforeAdding: Flag to clear existing entries before adding new ones.

Adding Directories for Indexing

Overview: Add directories containing documents to be indexed by the search network’s master node.

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

public class AddDirectoriesForIndexing {
    public static void run(SearchNetworkNode masterNode) {
        String documentsPath = "YOUR_DOCUMENT_DIRECTORY/DocumentsPath";

        IndexingDocuments.addDirectories(masterNode, documentsPath);
        
        // Directory addition logic
    }
}
  • Key Steps:
    • Define the path for document directories.
    • Use addDirectories to update indexing.

Performing Text Search in Network

Overview: Conduct text searches across a distributed search network efficiently.

import com.groupdocs.search.scaling.*;

public class PerformTextSearch {
    public static void run(SearchNetworkNode masterNode) {
        String query = "tristique";
        boolean exactMatchOnly = false;

        TextSearchInNetwork.searchAll(masterNode, query, exactMatchOnly);
        exactMatchOnly = true;
        TextSearchInNetwork.searchAll(masterNode, query, exactMatchOnly);
        
        // Search execution logic
    }
}
  • Parameters:
    • query: The text to search for.
    • exactMatchOnly: Flag to control match specificity.

Closing Network Nodes

Overview: Properly close all active nodes in the network to free resources.

import com.groupdocs.search.scaling.*;

public class CloseNetworkNodes {
    public static void run(SearchNetworkNode[] nodes) {
        for (SearchNetworkNode node : nodes) {
            node.close();
            
            // Node closure logic
        }
    }
}
  • Key Considerations:
    • Ensure all resources are released properly to avoid memory leaks.

FAQ’s

  1. How does deploying multiple nodes improve search performance?
    Distributed nodes allow parallel processing, reduce load, and provide faster, scalable searches across large datasets.

  2. Can I add synonyms dynamically without reindexing?
    Yes, synonyms can be added or modified at runtime via the indexer’s dictionary, often without a full reindex.

  3. Is it necessary to subscribe to node events, and why?
    Subscribing helps monitor network health, node status, and handles events for better network management and stability.

  4. What are best practices for managing node resources?
    Regularly close idle nodes, monitor memory usage, and properly release resources to prevent leaks and ensure smooth operations.

  5. Can GroupDocs.Search handle non-text formats, like PDFs or images?
    Yes, it supports extracting and indexing various formats, including PDFs, Office documents, and images with OCR capabilities.
