License Acquisition

To try out GroupDocs.Search:

  • Free Trial: Start with a free trial to test core functionalities.
  • Temporary License: Obtain a temporary license for extended access during development.
  • Purchase: Consider purchasing a full license if the solution fits your needs.

Basic Initialization and Setup

Initialize GroupDocs.Search by creating an index in your desired directory:

import com.groupdocs.search.*;

public class CreateIndex {
    public static void main(String[] args) {
        String indexFolder = "YOUR_DOCUMENT_DIRECTORY\\output\\AdvancedUsage\\Searching\\SearchByChunks";
        // Creating an index in the specified folder
        Index index = new Index(indexFolder);
    }
}

Implementation Guide

Now, let’s break down each feature and its implementation step-by-step.

1. Creating an Index

Overview: This step involves setting up a directory where your search index will reside.

  • Step 1: Define the Index Folder
    String indexFolder = "YOUR_DOCUMENT_DIRECTORY\\output\\AdvancedUsage\\Searching\\SearchByChunks";
  • Step 2: Create the Index
    Index index = new Index(indexFolder);

2. Adding Documents to Index

Overview: Add documents from multiple folders into your newly created index.

  • Step 1: Define Document Folders
    String documentsFolder1 = "YOUR_DOCUMENT_DIRECTORY";
String documentsFolder2 = "YOUR_DOCUMENT_DIRECTORY";
String documentsFolder3 = "YOUR_DOCUMENT_DIRECTORY";
  • Step 2: Add Documents to the Index
    index.add(documentsFolder1);
index.add(documentsFolder2);
index.add(documentsFolder3);

Overview: Enable chunk-based searching by configuring search options.

  • Step 1: Create a SearchOptions Instance
    SearchOptions options = new SearchOptions();
  • Step 2: Enable Chunk Search
    options.setChunkSearch(true);

Overview: Execute an initial search using chunk-based options.

  • Step 1: Define the Query
    String query = "invitation";
  • Step 2: Perform the Search
    SearchResult result = index.search(query, options);

Overview: Continue searching in subsequent chunks after the initial search.

  • Step 1: Check for Next Chunk Token
    while (result.getNextChunkSearchToken() != null) {
    result = index.searchNext(result.getNextChunkSearchToken());
}

Practical Applications

Chunk-based searches are invaluable in scenarios such as:

  1. Legal Document Management: Quickly locate relevant clauses or references across thousands of files.
  2. Customer Support Systems: Enhance response times by efficiently searching through customer queries and solutions.
  3. Research Data Analysis: Streamline the process of finding pertinent data within extensive research datasets.

Performance Considerations

To optimize performance when using GroupDocs.Search:

  • Memory Management: Ensure your Java environment is configured to handle large indexes efficiently.
  • Resource Usage: Monitor CPU and memory usage during indexing and searching operations.
  • Best Practices: Regularly update your index and clear outdated data to maintain search speed.

Conclusion

By following this guide, you’ve learned how to implement chunk-based searches using GroupDocs.Search for Java. This powerful feature allows you to manage large datasets effectively, enhancing both performance and usability in real-world applications.
