To echo what everyone else is saying, get FZF. Most of these linux productivity things are just some dumb pet project that solves a specific problem that a specific person finds annoying. FZF is not this - it makes something you do hundreds of times a day (history and file opening on zsh, bash, fish, whatever) indisputably better. If you find yourself sitting there tapping ctrl+r multiple times like an idiot for some thing that may or may not be there, do your stubborn beardy ass a favour and install fzf.

You can implement some or all of the tips in this HN post, it'll make fzf results better.
