Smart Search plugin for CJF?

CjForum has Topics finder plugin bundled. Just enable it.

Thanks! do I need to thave Search - cjForum enabled too? Or is that for the 'old' (non-Finder) search engine?

Here is what is confusing me ( I have disabled all the plugins that are labeled with folder 'Search', rather than folder 'Finder'...)

It seems that the Topics finder plugin says that it is is for CommunityAnswers, not for CJforums. 

(see attachment)

Does each app separately filter the results accordingly ( do not want to mix them...)

And I right in supposing that Content- Smart Search plugin can be unpublished ( the only 'Finder' searching on our site is going to be for corejoomla apps, we use a google search to search actual article contents...)

Please advise, thanks!

The plugin was cloned from the community answers but the text was not changed. It searches topics.
