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

Implementation Guide

Creating and Managing an Index

Overview

Creating a document index organizes your documents for quick search and retrieval. GroupDocs.Search makes this process seamless.

Steps:

  1. Define the Index Folder: Set up a folder path where your index will be stored.
    String indexFolder = "YOUR_DOCUMENT_DIRECTORY/Index";
    Index index = new Index(indexFolder);
    
  2. Initialize the Index: Create an instance of Index with the specified directory.

Managing Document Passwords in the Index Dictionary

Overview

Securely manage passwords for your documents within the index to ensure that only authorized users can access them.

Steps:

  1. Check Existing Passwords
    if (index.getDictionaries().getDocumentPasswords().getCount() > 0) {
        index.getDictionaries().getDocumentPasswords().clear();
    }
    
  2. Add a Password to a Document
    String documentPath = new File("YOUR_DOCUMENT_DIRECTORY/English.docx").getAbsolutePath();
    index.getDictionaries().getDocumentPasswords().add(documentPath, "123456");
    
  3. Retrieve and Remove a Password
    if (index.getDictionaries().getDocumentPasswords().contains(documentPath)) {
        String retrievedPassword = index.getDictionaries().getDocumentPasswords().getPassword(documentPath);
        index.getDictionaries().getDocumentPasswords().remove(documentPath);
    }
    
  4. Add Passwords to Multiple Documents
    index.getDictionaries().getDocumentPasswords().add("YOUR_DOCUMENT_DIRECTORY/English.docx", "123456");
    index.getDictionaries().getDocumentPasswords().add("YOUR_DOCUMENT_DIRECTORY/Lorem ipsum.docx", "123456");
    

Indexing Documents with Passwords

Overview

Index documents using pre-defined passwords to enable secure searches within your documents.

Steps:

  1. Add Documents to the Index
    String documentsFolder = "YOUR_DOCUMENT_DIRECTORY";
    index.add(documentsFolder);
    

Searching Within an Indexed Document

Overview

Perform powerful searches across indexed documents using GroupDocs.Search’s capabilities.

Steps:

  1. Define a Search Query and Execute It
    String searchQuery = "ipsum OR increasing";
    SearchResult searchResult = index.search(searchQuery);
    

Practical Applications

Explore these real-world applications to understand how GroupDocs.Search can be integrated into your projects:

  1. Enterprise Document Management Systems: Streamline document retrieval in large organizations.
  2. Content Management Platforms: Enhance content discoverability with advanced search features.
  3. Legal Document Archives: Securely index sensitive documents for easy access by authorized personnel.

Performance Considerations

  • Optimize Indexing: Use parallel processing where possible to speed up the indexing process.
  • Memory Management: Monitor resource usage during indexing and searching operations.
  • Index Maintenance: Regularly update your indexes to reflect changes in document collections.
