When you create a language project, a reversal index is automatically generated for the default (top) analysis writing system. Later, if you add another analysis writing system, a reversal index is automatically added.
You use the Configure Reversal Index dialog box to configure the view that corresponds to that analysis writing system.
You can use the Manage Reversal Index Views dialog box to duplicate a view.
Then you can configure each view of the same language differently.
