Provide Search and Replace Functionality for custom VS2010 ToolWindow

Good afternoon,

we have a VS2010 Package/Add-in with several custom ToolWindow implementations and for one of them want to provide a Search & Replace functionality and I was wondering how I would do that, in particular what interfaces etc to implement. However, these ToolWindows are NOT editor windows, just as a side-note. Ideally we'd like to use the default VS Search & Replace dialogs (rather than implement our own and override the VS search & replace etc commands).

I am speaking about this particular dialog:

.. and the Replace functionality of it:

Cheers and thanks,
