Keyboard layout correction Leave feedback

When entering search queries, users of your software may make input errors, forgetting to switch the desired keyboard layout. For example, entering the word ‘Einstein’ in the Russian keyboard layout will result in the word ‘Уштыеушт’ appearing.

To automatically fix such misprints, the keyboard layout correction feature can be used. To enable this feature, you must set the true value for the Enabled property in the search options. By default, this feature is disabled.

The following example demonstrates using of the keyboard layout correction feature.

C#

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 a search options object
SearchOptions options = new SearchOptions();
options.KeyboardLayoutCorrector.Enabled = true; // Enabling keyboard layout correction

// Search for word 'Уштыеушт' gives documents containing word 'Einstein'
SearchResult result = index.Search("Уштыеушт", options);
