In today’s data-driven world, retrieving relevant information from vast collections of documents is crucial. Boolean search provides a powerful way to refine and customize your search queries using logical operators like AND, OR, and NOT. By leveraging these operators, you can pinpoint the exact information you need, whether for data analysis, reporting, or content validation. With Search library, developers can easily perform Boolean search using C#, enabling precise results from indexed documents. This guide will demonstrate how to implement full-text search with Boolean operators in C#, helping you unlock advanced search capabilities in your applications.
Steps to Perform Boolean Search using C#
- Prepare your development environment by integrating GroupDocs.Search for .NET to enable Boolean search functionality in C#
- Create an Index object to establish a storage area where your documents can be indexed and searched
- Utilize the Index.Add method to incorporate documents from a chosen directory into the index
- Execute the Index.Search method with Boolean operators such as AND, OR, or NOT to perform your search query
- Access the search results using the SearchResult method to review the details of the query matches
Boolean search is a powerful feature that enables precise data retrieval, you can seamlessly implement it in your applications. The process begins with creating an index using the Index class, which acts as a searchable storage area for your documents. Once the index is set up, you can populate it using the Index.Add method to include files from a specified directory. After indexing, perform Boolean searches using the Index.Search method, combining keywords with operators like AND, OR, and NOT to filter results accurately. For example, use AND to find documents containing all terms, OR for at least one term, and NOT to exclude terms. The results, returned in a SearchResult object, can be further processed for reporting, analytics, or integration into your application. This approach not only simplifies advanced document search but also ensures scalability and efficiency when you index documents for Boolean search in C#.
Code to Perform Boolean Search using C#
| using GroupDocs.Search; | |
| using GroupDocs.Search.Results; | |
| namespace PerformBooleanSearchUsingCSharp | |
| { | |
| internal class Program | |
| { | |
| static void Main(string[] args) | |

| string indexFolder = @"d:\MyIndex\"; | |
| string documentsFolder = @"d:\MyDocuments\"; | |
| // Creating an index in the specified folder | |
| Index index = new Index(indexFolder); | |
| // Indexing documents from the specified folder | |
| index.Add(documentsFolder); | |
| // Search with text query | |
| SearchResult result1 = index.Search("theory AND relativity"); | |
| // Search with object query | |
| SearchQuery wordQuery1 = SearchQuery.CreateWordQuery("theory"); | |
| SearchQuery wordQuery2 = SearchQuery.CreateWordQuery("relativity"); | |
| SearchQuery andQuery = SearchQuery.CreateAndQuery(wordQuery1, wordQuery2); | |
| SearchResult result2 = index.Search(andQuery); | |
| } | |
| } | |
| } |
Boolean search is a powerful tool for enhancing document search and retrieval capabilities in applications. By following the steps outlined in this guide, you can implement efficient and precise search functionality. Whether you need to audit large datasets, analyze text-based content, or manage document archives, the above method ensures flexibility and scalability. Moreover, by learning to build Boolean search logic in C#, you can further customize your applications to meet unique search requirements, providing a superior user experience. Start integrating this functionality into your projects today and unlock new possibilities for advanced document processing.
