{
    // Your redaction code here
}

This simple setup is all you need to begin using GroupDocs.Redaction.

Implementation Guide

Creating an Index

Overview:
Creating an index is the foundation of efficient document search operations. Let’s start by setting up a new index in a specified directory.

Step 1: Create the Index

using GroupDocs.Search;

string indexFolder = @"YOUR_DOCUMENT_DIRECTORY/AdvancedUsage/Indexing/DeleteIndexedPaths";
Index index = new Index(indexFolder);
// This line initializes an index at the provided folder path.

Adding Documents to the Index

Overview:
Adding documents is crucial for building a comprehensive search index. We’ll add files from specific directories.

Step 2: Add Document Folders

string documentsFolder1 = @"YOUR_DOCUMENT_DIRECTORY";
string documentsFolder2 = @"YOUR_DOCUMENT_DIRECTORY2";

index.Add(documentsFolder1);  // Adding the first folder of documents to the index
index.Add(documentsFolder2);  // Adding the second folder of documents to the index

Retrieving Indexed Paths

Overview:
To manage your indexed data, retrieving paths can help you verify which documents are included.

Step 3: Display Indexed Paths

string[] indexedPaths1 = index.GetIndexedPaths();
foreach (string path in indexedPaths1)
{
    Console.WriteLine(path); // Outputs the document paths
}

Deleting Indexed Paths

Overview:
There may be times when you need to remove specific documents from your index. Let’s see how this is done.

Step 4: Delete Specific Paths

using GroupDocs.Search.Options;

string[] pathsToDelete = { @"YOUR_DOCUMENT_DIRECTORY" };
DeleteResult deleteResult = index.Delete(pathsToDelete, new UpdateOptions());
// This deletes specified document paths from the index.

Retrieving Indexed Paths After Deletion

Overview:
After deletion operations, you might want to verify which documents remain indexed.

Step 5: Verify Remaining Paths

string[] indexedPaths2 = index.GetIndexedPaths();
foreach (string path in indexedPaths2)
{
    Console.WriteLine(path); // Displays remaining paths after deletion
}

Practical Applications

  1. Document Management Systems: Use indexing to quickly search and retrieve documents.
  2. Legal Document Review: Efficiently redact sensitive information before indexing.
  3. Archival Solutions: Maintain organized archives with searchable indexes.
  4. Content Management Platforms: Enhance search capabilities for content-heavy sites.
  5. Data Compliance Audits: Ensure compliance by managing what’s indexed and accessible.

Performance Considerations

  • Optimize Indexing: Regularly update your index to reflect the latest document changes.
  • Resource Management: Monitor memory usage, especially with large indexes.
  • Best Practices: Use batching for adding documents to minimize resource spikes.
