Searching by site visitors – let them restrict content types?

Hi guys,

I really want to give users some options when they search the site. I'd like them to be able to tick or untick boxes to show/hide content and categories. So they can choose to only search Authors or Posts or Comments.

I'd also like them to be able to organise the search with the most recent items first.

Do your search plugins play nicely with any other plugins that do this? I've been searching online for this solution (which I assumed would be very common/desired) but am drawing a blank!

Thanks,
Mike
