I don’t know if the fact that it can show Wikipedia results, and that you can connect it to your Google account (to show cloud files from Drive and such in the search results) plays a role too

Apparently it does, according to a metadata link from the F-Droid's own repo shared by @pipes@sh.itjust.works 's reply, also pointed out by @BearOfaTime@lemm.ee

On a sidenote, searching your own Owncloud or Nextcloud is supported too.

Thanks, OP confirmed this, sounds awesome.

Thanks for explaining it further! :)

Huh, thanks for pointing that out. Sorry for missing that, sometimes I need to read more than once to spot details I guess.

Thanks, but my question is why and/or if it is common for a launcher to need that (also I didn't know there was more details to it on F-Droid repo, thanks for sharing the metadata link)

Kvaesitso

A search-focused, free and open source launcher for Android

Kvaesitso is a launcher application for Android which replaces the device's default home screen. It has been built from scratch, meaning it is not based on the AOSP launcher (like many other third party launchers) nor does it try to recreate this launcher. Instead, Kvæsitso follows its own concepts.The main feature is a global search which does not only let you search on device for apps, contacts, and calendar events, but also on web services like Wikipedia or your Nextcloud Instance. Additionally it includes some useful tools, for example a calculator and a unit converter. You are looking for a document or an information? Just search for it and Kvæsitso shows you the fastest way to it.

Anti-Features

This app promotes or depends entirely on a non-free network service

I'm not knowledgeable on how launchers work but why is this needed to communicate to a network service?
