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 for the phrase in text form
// the first caret character at the beginning indicates that this is a regular expression search query
string query1 = "^^(.)\\1{1,}";
// search for two or more identical characters at the beginning of a word
SearchResult result1 = index.Search(query1); 

// search for the phrase in object form
// search for two or more identical characters at the beginning of a word
SearchQuery query2 = SearchQuery.CreateRegexQuery("^(.)\\1{1,}");
SearchResult result2 = index.Search(query2);

Spell Check with Smart Search via C# Code

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);

// creating search options instance
SearchOptions options = new SearchOptions();
// enabling the spelling correction
options.SpellingCorrector.Enabled = true;
// setting the maximum number of mistakes
options.SpellingCorrector.MaxMistakeCount = 1;
// enabling the option for only the best results of the spelling correction
options.SpellingCorrector.OnlyBestResults = true;

// search for the word "Rleativity" containing a spelling error
// the word "Relativity" will be found that differs from the search query in two transposed letters
SearchResult result = index.Search("Rleativity", options);
