        System.out.println("Index created at: " + indexFolder);
    }
}

Implementation Guide

Creating an Index

Creating a search index is the first step toward enabling efficient document retrieval.

Overview

A search index allows quick searches across large volumes of data. By indexing documents, you prepare them for fast querying.

Steps to Create an Index

  1. Define the Output Directory: Specify where your index will be stored for organized access and management.
  2. Initialize the Index: Use the Index class from GroupDocs.Search to create the index in your specified directory.
import com.groupdocs.search.Index;

public class CreateIndexExample {
    public static void main(String[] args) {
        // Define the path for the output index directory
        String indexFolder = "YOUR_OUTPUT_DIRECTORY/HelloWorld";
        
        // Creating an index in the specified folder.
        Index index = new Index(indexFolder);
        System.out.println("Index created at: " + indexFolder);
    }
}

Adding Documents to the Index

Once your index is set up, populate it with documents for search operations.

Overview

Adding documents to an index prepares them for search queries. This step involves specifying the directory containing your documents and using GroupDocs.Search methods to add them.

Steps to Add Documents

  1. Specify Document Directory: Define where your source documents are located.
  2. Add Documents to Index: Use the add() method from GroupDocs.Search to include all documents from the specified directory into your index.
import com.groupdocs.search.Index;

public class AddDocumentsToIndexExample {
    public static void main(String[] args) {
        // Define the path for the output index directory and documents folder
        String indexFolder = "YOUR_OUTPUT_DIRECTORY/HelloWorld";
        String documentsFolder = "YOUR_DOCUMENT_DIRECTORY";
        
        // Create an index in the specified folder.
        Index index = new Index(indexFolder);
        
        // Adding documents from the specified folder to the index.
        index.add(documentsFolder);
        System.out.println("Documents added to index.");
    }
}

Searching within the Index

With your documents indexed, perform searches efficiently.

Overview

Executing a search query on an index allows rapid data retrieval. This step demonstrates how to leverage GroupDocs.Search for querying indexed content.

  1. Define Your Query: Determine what you are searching for within the indexed documents.
  2. Execute the Search: Use the search() method from GroupDocs.Search to perform your query and retrieve results.
import com.groupdocs.search.Index;
import com.groupdocs.search.results.SearchResult;

public class SearchIndexExample {
    public static void main(String[] args) {
        // Define the path for the output index directory
        String indexFolder = "YOUR_OUTPUT_DIRECTORY/HelloWorld";
        
        // Create an index in the specified folder.
        Index index = new Index(indexFolder);
        
        // Performing a search query on the indexed documents.
        SearchResult result = index.search("Lorem");
        
        System.out.println("Search completed. Number of results: " + result.getDocumentCount());
    }
}
