Advanced Document Search and Indexing with .NET API

// Create an index
Index index = new Index("C:/IndexFolder");
index.Add("C:/DocumentFolder");

// Set up search options
SearchOptions options = new SearchOptions();
options.FuzzySearch.Enabled = true;
options.FuzzySearch.FuzzyAlgorithm = new TableDiscreteFunction(3);

// Search for documents containing the word 'water' or the phrase 'Lorem ipsum'
string query = "water OR \"Lorem ipsum\"";
SearchResult result = index.Search(query, options);

// Process search result
Console.WriteLine("Document: " + document.DocumentInfo.FilePath);
Console.WriteLine("Occurrences: " + document.OccurrenceCount);
for (int i = 0; i < result.DocumentCount; i++) {
    FoundDocument document = result.GetFoundDocument(i);
    Console.WriteLine("Document: " + document.DocumentInfo.FilePath);
    Console.WriteLine("Occurrences: " + document.OccurrenceCount);
    }

// Create an index
Index index = new Index("c:/IndexFolder");
index.Add("c:/DocumentFolder");

// Search for the phrase in text form

// The first caret character at the beginning indicates that this is a regular expression search query
string query = "^^(.)\\1{1,}";
// Search for two or more identical characters at the beginning of a word
SearchResult result = index.Search(query);
