For those willing to pay. Kagi has been a total breath of fresh air.
I rarely have issues with content farms taking up the first page of results, all the Google search operators (at least the ones i relied on) with consistently again, you can block and/or weight results (no shitty pintrist results). It took me a while to come to grips with paying but so far it’s been very worth it.
Disclaimer: i have only been using it for about 2 or 3 months.
Pihole can do this out of the box by going to the dns settings and adding a host. Alternatively, if your pihole is also your dhcp provider, you can set the hostname on each and pi hole should resolve it.
