GroupDocs.Search for .NET boasts support for various query types, such as fuzzy, regular expression, wildcard, and boolean, to help you conveniently search through indexes to find the required information. With excellent search and indexing capabilities, this powerful API enables programmers to enhance search operations while handling large and complex data sets. One of the prominent features of the API is applying different filters to the documents when indexing them. We will review how to use the .NET text search API for quickly performing boolean search and filtering documents within the .NET search and indexing solutions.
Boolean search allows the use of AND, NOT, and OR boolean operators in simple and nested search queries. Developers can use boolean search to combine multiple search queries for data retrieval. This C# coding example explains using the AND operator for data search.
string indexFolder = @"c:\MyIndex\";
string documentsFolder = @"c:\MyDocuments\";
// Creating an index in the specified folder
Index index = new Index(indexFolder);
// Indexing documents from the specified folder
index.Add(documentsFolder);
// Search with a 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);
Applying filters to search indexes makes data sorting and analysis more efficient. You can apply document filters to indexes using the .NET indexing API and enhance search performance with advanced document indexing. Please check out the following example to learn more.
string indexFolder = @"c:\MyIndex\";
string documentsFolder = @"c:\MyDocuments\";
// Creating a filter that skips documents with extensions '.doc', '.docx', '.rtf'
IndexSettings settings = new IndexSettings();
DocumentFilter fileExtensionFilter = DocumentFilter.CreateFileExtension(".doc", ".docx", ".rtf"); // Creating file extension filter that allows only specified extensions
DocumentFilter invertedFilter = DocumentFilter.CreateNot(fileExtensionFilter); // Inverting file extension filter to allow all extensions except specified ones
settings.DocumentFilter = invertedFilter;
// Creating an index in the specified folder
Index index = new Index(indexFolder, settings);
// Indexing documents
index.Add(documentsFolder);
