Getting the current search options (FindOptions)

Hi,

I am writing a Visual Studio 2012 extension and I would like to perform some search operations automatically, either through ITextSearchService or ITextSearchNavigator.

Both require that I pass a FindOptions enumeration to set the search options (case-sensitivity, whole-word matching, etc.).

I would like my operation to use the same options as set in the default search dialog.
Is there a way for me to retrieve the current values for these options?
(Or possibly a way to retrieve a reference to an already set-up ITextSearchNavigator?)

Thanks
