Implementation Guide

This section is divided by feature, detailing each implementation step for using AND, OR, and NOT operators in your queries.

Feature: Operator AND

Overview

The ‘AND’ operator allows you to search for documents that contain all specified terms. This feature helps pinpoint precise information across multiple criteria.

Step 1: Set Up Indexing Folder
using GroupDocs.Search;

string indexFolder = "YOUR_DOCUMENT_DIRECTORY/OperatorAnd";
Step 2: Create and Add Documents to the Index
Index index = new Index(indexFolder);
index.Add("YOUR_DOCUMENT_DIRECTORY/DocumentsPath");
Step 3: Perform Search with ‘AND’ Operator

Text Query

string query1 = "comfort AND promotion";
SearchResult result1 = index.Search(query1);

Object Query

using GroupDocs.Search;

SearchQuery wordQuery1 = SearchQuery.CreateWordQuery("comfort");
SearchQuery wordQuery2 = SearchQuery.CreateWordQuery("promotion");
SearchQuery andQuery = SearchQuery.CreateAndQuery(wordQuery1, wordQuery2);

SearchResult result2 = index.Search(andQuery);

Feature: Operator OR

Overview

The ‘OR’ operator broadens your search to include documents containing any of the specified terms.

Step 1: Set Up Indexing Folder
string indexFolderOr = "YOUR_DOCUMENT_DIRECTORY/OperatorOr";
Step 2: Create and Add Documents to the Index
Index indexOr = new Index(indexFolderOr);
indexOr.Add("YOUR_DOCUMENT_DIRECTORY/DocumentsPath");
Step 3: Perform Search with ‘OR’ Operator

Text Query

string query1Or = "comfort OR neque";
SearchResult result1Or = indexOr.Search(query1Or);

Object Query

using GroupDocs.Search;

SearchQuery wordQuery1Or = SearchQuery.CreateWordQuery("comfort");
SearchQuery wordQuery2Or = SearchQuery.CreateWordQuery("neque");

SearchQuery orQuery = SearchQuery.CreateOrQuery(wordQuery1Or, wordQuery2Or);

SearchResult result2Or = indexOr.Search(orQuery);

Feature: Operator NOT

Overview

The ‘NOT’ operator excludes documents containing specific terms, refining your search results.

Step 1: Set Up Indexing Folder
string indexFolderNot = "YOUR_DOCUMENT_DIRECTORY/OperatorNot";
Step 2: Create and Add Documents to the Index
Index indexNot = new Index(indexFolderNot);
indexNot.Add("YOUR_DOCUMENT_DIRECTORY/DocumentsPath");
Step 3: Perform Search with ‘NOT’ Operator

Text Query

string query1Not = "sportsman AND NOT Kynynmound";
SearchResult result1Not = indexNot.Search(query1Not);

Object Query

using GroupDocs.Search;

SearchQuery wordQuery1Not = SearchQuery.CreateWordQuery("sportsman");
SearchQuery wordQuery2Not = SearchQuery.CreateWordQuery("Kynynmound");

SearchQuery notQuery = SearchQuery.CreateNotQuery(wordQuery2Not);
SearchQuery andQueryNot = SearchQuery.CreateAndQuery(wordQuery1Not, notQuery);

SearchResult result2Not = indexNot.Search(andQueryNot);

Practical Applications

Here are some real-world applications of using GroupDocs.Redaction for .NET with complex queries:

  1. Legal Document Management: Quickly find all documents containing specific legal terms while excluding irrelevant ones.
  2. Research Data Analysis: Retrieve academic papers that discuss multiple key concepts simultaneously, filtering out unrelated topics.
  3. Corporate Compliance: Efficiently search through compliance records to ensure all necessary regulations are met.

Performance Considerations

To optimize the performance of your GroupDocs.Redaction implementation:

  • Regularly update and maintain your indexes for quick access.
  • Utilize memory management best practices in .NET to handle large document sets efficiently.
  • Monitor resource usage to prevent bottlenecks during intensive search operations.

Conclusion

By mastering AND, OR, and NOT queries with GroupDocs.Redaction for .NET, you enhance your ability to manage and retrieve information from extensive document collections effectively. As you continue exploring the capabilities of this powerful tool, consider experimenting with more complex query combinations to further refine your searches.
