On KDE, it’s just one of the suggestions, I believe, that you could search this term on the web. If you trigger that suggestion, it then opens the web browser to do the search.
As such, searching “terminal” wouldn’t yield a suggestion from a web result that matches, but I’m pretty sure applications are prioritized above other results either way.






It shows up as “Terminal” in the search results, so I imagine that’s what it matches against, even if it is colloquially referred to as “Windows Terminal”…
