Well, sure, but assume you're new and you don't know that. You can usually search for "man ip" to get close, but that usually just gets you a technical reference for an experienced user (the man page) and not a tutorial, introduction, or training doc for someone learning a new tool. "ip command tutorial" works well, though the results are still rather mixed. I get Cisco and Windows results as well until I search "ip command tutorial linux".

The point is that searching for "ifconfig tutorial" is going to give you what you want, while "ip route" is probably going to get you Cisco documentation, honestly. Even something like "parse ip output" is going to give you a mix of results from Linux, Windows, or web services while "parse ifconfig output" is a lot more clear.

"ip" is simply a saturated keyword, making it a bad keyword.
