The example demonstrates how to merge segments of an index with particular merge options.
string indexFolder = @"c:\MyIndex\";
string documentsFolder1 = @"c:\MyDocuments1\";
string documentsFolder2 = @"c:\MyDocuments2\";
string documentsFolder3 = @"c:\MyDocuments3\";

Index index = new Index(indexFolder); // Creating index in the specified folder

index.Add(documentsFolder1); // Indexing documents from the specified folder
index.Add(documentsFolder2); // Each call to Add creates at least one new segment in the index

MergeOptions options = new MergeOptions();
options.IsAsync = true; // Asynchronous operation
options.Cancellation = new Cancellation(); // Creating cancellation object

// Merging segments of the index
index.Optimize(options); // This method will return before the operation is completed

options.Cancellation.CancelAfter(10000); // Setting maximum duration of the operation to 10 seconds
