Before implementing these powerful features, let’s review the prerequisites!

Prerequisites

Before you begin, ensure that you have met the following requirements:

Required Libraries and Dependencies

To use GroupDocs.Search in Java, set up your project with Maven dependencies. Include the GroupDocs repository and dependency in your pom.xml file:

<repositories>
   <repository>
      <id>repository.groupdocs.com</id>
      <name>GroupDocs Repository</name>
      <url>https://releases.groupdocs.com/search/java/</url>
   </repository>
</repositories>

<dependencies>
   <dependency>
      <groupId>com.groupdocs</groupId>
      <artifactId>groupdocs-search</artifactId>
      <version>25.4</version>
   </dependency>
</dependencies>

Alternatively, download the latest version directly from GroupDocs.Search for Java releases.

Environment Setup Requirements

Ensure you have a compatible JDK installed (Java 8 or higher recommended). Your development environment should support Maven projects.

Knowledge Prerequisites

Familiarity with Java programming and basic knowledge of Maven project setup will be beneficial to follow along effectively.

Setting Up GroupDocs.Search for Java

Setting up your Java project with GroupDocs.Search involves a few key steps:

Maven Setup: Add the necessary repository and dependency in your pom.xml as shown above.
License Acquisition: Obtain a temporary license to explore the full features of GroupDocs.Search without any limitations. Visit GroupDocs Temporary License for more details.

Basic Initialization

To initialize GroupDocs.Search in your Java application, start by setting up a basic configuration:

import com.groupdocs.search.*;

public class SearchSetup {
    public static void main(String[] args) {
        // Create an index
        Index index = new Index("YOUR_INDEX_DIRECTORY");
        
        // Add documents to the index
        index.add("YOUR_DOCUMENT_DIRECTORY");

        System.out.println("Indexing completed.");
    }
}

Replace "YOUR_INDEX_DIRECTORY" and "YOUR_DOCUMENT_DIRECTORY" with your actual directories. This simple setup initializes an index and adds documents, preparing you for more complex operations.

Implementation Guide

We’ll break down the implementation into three main features: Configuration Setup, Search Network Deployment, and Network Document Retrieval.

Feature 1: Configuration Setup

Overview

This feature demonstrates configuring a search network with a base path and port. It’s crucial for setting up your indexing environment.

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

public class ConfigurationSetup {
    public static void main(String[] args) {
        String basePath = "YOUR_DOCUMENT_DIRECTORY"; // Set your document directory here
        int basePort = 49108; // Port number for the configuration
        
        // Configure the search network with provided path and port.
        Configuration configuration = ConfiguringSearchNetwork.configure(basePath, basePort);
    }
}

Explanation: The ConfiguringSearchNetwork.configure method sets up your environment using a specified document directory and port. Customize these parameters as needed for your project.

Feature 2: Search Network Deployment

Overview

Deploying the search network involves initializing nodes that will handle document indexing and retrieval operations.

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

public class SearchNetworkDeploymentFeature {
    public static void main(String[] args) {
        String basePath = "YOUR_DOCUMENT_DIRECTORY"; // Set your document directory here
        int basePort = 49108; // Port number for deployment
        
        Configuration configuration = ConfiguringSearchNetwork.configure(basePath, basePort);
        
        // Deploy the search network using given path and port.
        SearchNetworkNode[] nodes = SearchNetworkDeployment.deploy(basePath, basePort, configuration);
    }
}

Explanation: The deploy method initializes nodes based on your configuration. Each node can independently handle part of the indexing process, enabling scalability.

Feature 3: Network Document Retrieval

Overview

Retrieve documents from a search network that match specified text criteria.

import com.groupdocs.search.common.*;
import com.groupdocs.search.scaling.*;
import java.util.ArrayList;
import java.util.Arrays;

public class NetworkDocumentRetrievalFeature {
    public static void main(String[] args) {
        // Assuming masterNode is already initialized and contains documents.
        SearchNetworkNode masterNode = null;  // Placeholder: Initialize your search network node here
        String containsInPath = "English.txt";
        
        getDocumentText(masterNode, containsInPath);
    }

    public static void getDocumentText(SearchNetworkNode node, String containsInPath) {
        Searcher searcher = node.getSearcher();
        ArrayList<NetworkDocumentInfo> documents = new ArrayList<>();
        int[] shardIndices = node.getShardIndices();

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

            for (NetworkDocumentInfo info : infos) {
                NetworkDocumentInfo[] items = searcher.getIndexedDocumentItems(info);
                documents.addAll(Arrays.asList(items));
            }
        }

        for (NetworkDocumentInfo document : documents) {
            if (document.getDocumentInfo().toString().contains(containsInPath)) {
                StringOutputAdapter outputAdapter = new StringOutputAdapter(OutputFormat.PlainText);
                searcher.getDocumentText(document, outputAdapter);

                System.out.println(outputAdapter.getResult());
                break;
            }
        }
    }
}

Explanation: This feature iterates over shards to find documents containing the specified text. The searcher.getDocumentText method extracts and displays matched content.

Practical Applications

Enterprise Document Management: Streamline document retrieval in large organizations, enhancing productivity.
