  2. Follow the instructions provided for applying your license in your application.

Basic Initialization and Setup

Once installed, initialize GroupDocs.Redaction in your project:

using GroupDocs.Redaction;

// Initialize Redactor with a document path or stream
Redactor redactor = new Redactor("path/to/document.pdf");

Implementation Guide

Let’s delve into the practical implementation of modifying and adding attributes to documents.

Feature 1: Change Document Attributes

This feature allows you to modify existing attributes within your indexed documents, enhancing searchability and document management.

Overview

Modifying document attributes can be crucial for customizing how information is categorized or accessed. This section demonstrates adding a new attribute to all documents, removing one from the first document, and adding multiple attributes to another specific document.

Step 1: Initialize Index

Begin by setting up your index, which will house the document metadata:

using GroupDocs.Search.Common;
using GroupDocs.Search.Options;
using GroupDocs.Search.Results;

Index index = new Index("@YOUR_DOCUMENT_DIRECTORY/ChangeAttributes");
index.Add("@YOUR_DOCUMENT_DIRECTORY/DocumentsPath");
Step 2: Modify Attributes

Utilize an AttributeChangeBatch to batch process attribute changes:

DocumentInfo[] documents = index.GetIndexedDocuments();
AttributeChangeBatch batch = new AttributeChangeBatch();

// Adding "public" to all documents
batch.AddToAll("public");

// Removing "public" from the first document
batch.Remove(documents[0].FilePath, "public");

// Adding "main" and "key" to the first document
batch.Add(documents[0].FilePath, "main", "key");
index.ChangeAttributes(batch);
Step 3: Search with Attribute Filters

Configure search options to filter documents based on attributes:

SearchOptions options = new SearchOptions();
options.SearchDocumentFilter = SearchDocumentFilter.CreateAttribute("main");

// Perform search
string query = "length";
SearchResult result = index.Search(query, options);

Feature 2: Add Attributes During Indexing

This feature focuses on enhancing the indexing process by adding attributes to documents as they are indexed.

Overview

Adding attributes during indexing can optimize document categorization from the get-go. This section shows how to add specific attributes to a targeted document while it’s being indexed.

Step 1: Set Up Event Handler for Indexing

Attach an event handler to customize attribute addition:

Index index = new Index("@YOUR_DOCUMENT_DIRECTORY/AddAttributesDuringIndexing");

index.Events.FileIndexing += (sender, args) => {
    if (args.DocumentFullPath.EndsWith("Lorem ipsum.pdf")) {
        // Specify attributes for this document
        args.Attributes = new string[] { "main", "key" };
    }
};

// Add documents to index
index.Add("@YOUR_DOCUMENT_DIRECTORY/DocumentsPath");

As before, set up search options to utilize the newly added attributes:

SearchOptions options2 = new SearchOptions();
options2.SearchDocumentFilter = SearchDocumentFilter.CreateAttribute("main");

// Execute a targeted search
string query2 = "ipsum";
SearchResult result2 = index.Search(query2, options2);

Practical Applications

Here are some real-world scenarios where managing document attributes becomes invaluable:

  1. Legal Document Management: Automatically categorize contracts based on specific terms or clauses.
  2. Medical Records Organization: Add patient-specific attributes to streamline retrieval and privacy management.
  3. E-commerce Product Cataloging: Tag products with dynamic attributes like availability or discount status during inventory indexing.

Integration possibilities extend to CRM systems, cloud storage solutions, and custom enterprise applications requiring robust document handling capabilities.

Performance Considerations

Optimizing performance when working with large datasets is crucial:

  • Batch Processing: Use AttributeChangeBatch for bulk attribute modifications.
  • Selective Indexing: Only index documents that require attribute changes or searches to save resources.
  • Memory Management: Dispose of objects like SearchResult and Redactor instances promptly to free up memory.

Conclusion

In this tutorial, we’ve explored how to effectively manage document attributes using GroupDocs.Redaction and GroupDocs.Search. These tools not only enhance the security and accessibility of your documents but also open new possibilities for data management within .NET applications.

To continue exploring, consider delving deeper into other features offered by GroupDocs libraries or integrating these functionalities into larger projects.
