I remember a search, where the search results could be shown as threads. So one didn't had to read through a hundred posts in one thread, but could see only the threads and read them or not.
A search which gives su many results, that one reads them, looks quite unproductive to me.

You can do this on feeds, not on search. Searches will search content items and comments.

But we could do this on searches and we would like to do that again. It's much easier to find, what i was looking for in 20 threads instead of 200 posts.
