Basic Initialization and Setup

To initialize GroupDocs.Search in your Java application, create an instance of Index pointing to the directory where you wish to store the index files:

import com.groupdocs.search.*;

public class InitializeSearch {
    public static void main(String[] args) {
        String indexFolder = "YOUR_OUTPUT_DIRECTORY\\AdvancedUsage\\Indexing";
        Index index = new Index(indexFolder);
        System.out.println("GroupDocs.Search initialized successfully!");
    }
}

Implementation Guide

In this section, we will cover the key features of GroupDocs.Search: creating an index, adding documents, and retrieving indexing reports.

Creating an Index

Overview

Creating an index is the first step in enabling search capabilities for your document collections. This feature allows you to specify a folder where all index data will be stored.

import com.groupdocs.search.*;

public class CreateIndexFeature {
    public static void main(String[] args) {
        String indexFolder = "YOUR_OUTPUT_DIRECTORY\\AdvancedUsage\\Indexing\\CreateIndex";
        Index index = new Index(indexFolder);
        System.out.println("Index created at: " + indexFolder);
    }
}

Explanation: The Index constructor takes a folder path as its parameter. This is where the index data will be stored and managed.

Adding Documents to Index

Overview

Once your index is created, you can start adding documents from specified directories to enhance search capabilities.

import com.groupdocs.search.*;

public class AddDocumentsToIndexFeature {
    public static void main(String[] args) {
        String indexFolder = "YOUR_OUTPUT_DIRECTORY\\AdvancedUsage\\Indexing\\AddDocuments";
        String documentsFolder1 = "YOUR_DOCUMENT_DIRECTORY";
        String documentsFolder2 = "YOUR_DOCUMENT_DIRECTORY2";

        Index index = new Index(indexFolder);
        
        index.add(documentsFolder1);
        index.add(documentsFolder2);

        System.out.println("Documents added to the index successfully!");
    }
}

Explanation: The add() method allows you to specify directories containing documents that need to be indexed. This step is crucial for updating and maintaining your search database.

Getting and Displaying Indexing Reports

Overview

After adding documents, it’s useful to retrieve indexing reports to monitor the indexing process and gather statistics about the indexed data.

import com.groupdocs.search.*;

public class GetIndexingReportsFeature {
    public static void main(String[] args) {
        String indexFolder = "YOUR_OUTPUT_DIRECTORY\\AdvancedUsage\\Indexing\\GetReports";

        Index index = new Index(indexFolder);
        
        IndexingReport[] reports = index.getIndexingReports();
        
        for (IndexingReport report : reports) {
            System.out.println("Time: " + report.getStartTime());
            System.out.println("Duration: " + report.getIndexingTime());
            System.out.println("Documents total: " + report.getTotalDocumentsInIndex());
            System.out.println("Terms total: " + report.getTotalTermCount());
            System.out.println("Indexed documents size (MB): " + report.getIndexedDocumentsSize());
            System.out.println("Index size (MB): " + (report.getTotalIndexSize() / 1024.0 / 1024.0));
        }
    }
}

Explanation: This code snippet retrieves indexing reports, which provide valuable insights such as the start time of indexing, duration, total number of documents indexed, and index sizes.

Performance Considerations

To optimize performance when using GroupDocs.Search in Java:

Regularly update the index with new documents to keep search results relevant.
Monitor resource usage, especially memory, as indexing large datasets can be intensive.
Use best practices for Java memory management, such as setting appropriate heap sizes and garbage collection parameters.
