Browser History is spammed when you search something

[Kreijstal]

1. Go to https://tldr.ostera.io/
2. Search something by typping it
3. Look at the history log
   When you search for a command on the web frontend, every keystroke you type is pushed to the browser history so your history is cluttered with every key, you just typed.

Looks like instead of updating the location object directly, if navigation is done with the Web History API via history.replaceState, that would solve this issue.

As @mebiem suggests, perhaps a new state could be pushed only when a page is actually found?
