Filtering, not just highlighting, with ctrl-F

This is not a bug, but a feature request.

I am sending the stdout/stderr of several processes to a terminal and I need to filter the output to find what I am looking for. Right now, ctrl-f will highlight matches in yellow, that is good, but what I want to do is filter out all the unmatched lines and just show the matching lines, otherwise I have to comb/scroll through way too much output. Can iterm2 do this somehow? Would be an excellent feature. I also think it would be great toggle to search by regex or plaintext. There would have to be a button in the UI to toggle between those.

If the question is unclear please let me know, I might make a video describing what I want.
