Implementation Guide

In this section, we’ll explore two methods for implementing wildcard searches: Text Form and Object Form.

Wildcard Search in Text Form

Overview:

This feature allows you to search using simple text queries with wildcard patterns directly, making it intuitive and straightforward.

Implementation Steps:

1. Create an Index

Create an index where your documents are stored:

using GroupDocs.Search;

Index index = new Index("YOUR_DOCUMENT_DIRECTORY/WildcardSearch/QueryInTextForm");
  • Parameter: Directory path for storing the index.
2. Add Documents to Index

Add documents from a directory to be searchable:

index.Add("YOUR_DOCUMENT_DIRECTORY");

Perform searches using wildcard text patterns.

Example:

string query1 = "m???is";
SearchResult result1 = index.Search(query1);
// Searches for words like 'mauris', 'mollis', etc.
  • Explanation: The ? acts as a placeholder for any single character, allowing flexible search patterns.

Wildcard Search in Object Form

Overview:

Using the Object Form approach provides more control and precision by constructing wildcard patterns programmatically.

Implementation Steps:

1. Create an Index

As before, start by creating an index:

using GroupDocs.Search;
using GroupDocs.Search.Queries;

Index index = new Index("YOUR_DOCUMENT_DIRECTORY/WildcardSearch/QueryInObjectForm");
index.Add("YOUR_DOCUMENT_DIRECTORY");
2. Construct Patterns with WordPattern

Use the WordPattern object for more advanced searches.

Example:

using GroupDocs.Search.Queries;

WordPattern pattern1 = new WordPattern();
pattern1.AppendString("m")
        .AppendOneCharacterWildcard()
        .AppendOneCharacterWildcard()
        .AppendOneCharacterWildcard()
        .AppendString("is");
SearchQuery query1 = SearchQuery.CreateWordPatternQuery(pattern1);
SearchResult result1 = index.Search(query1);
// Searches for 'mauris', 'mollis', etc.
  • Explanation: This method breaks down the pattern into components, allowing detailed customization.

Practical Applications

  1. Legal Document Management: Quickly search through case files to find relevant documents using keyword patterns.
  2. Content Libraries: Enhance digital libraries by enabling users to find articles based on flexible search criteria.
  3. Data Archiving Systems: Efficiently retrieve archived data with specific search queries, improving retrieval times.

Performance Considerations

To optimize performance when using GroupDocs.Redaction:

  • Indexing Strategy: Regularly update your indexes to reflect new or modified documents for faster searches.
  • Resource Management: Monitor resource usage and optimize memory allocation in .NET applications to prevent bottlenecks.
  • Best Practices: Utilize asynchronous operations where possible to enhance responsiveness.

Conclusion

By integrating GroupDocs.Redaction with wildcard search capabilities, you can significantly improve the way your application handles document searches. This tutorial has equipped you with the knowledge to implement both Text and Object forms of wildcard searching effectively.
