Specifies how a text search is carried out in a System.Windows.Forms.RichTextBox control.
An application locates text in the System.Windows.Forms.RichTextBox control by calling the RichTextBox.Find(string) method of the System.Windows.Forms.RichTextBox control. This enumeration enables you to specify how the search is performed when the RichTextBox.Find(string) method is called. You can combine one or more values from this enumeration to specify more than one search option when calling the RichTextBox.Find(string) method.
