My own workflow (for all search engines) is to add a keyword search in Firefox. This is way better than the built-in "search engine" feature because it supports pretty much any website.

I have a bookmark for `https://kagi.com/search?token=...&q=%s` (you can get the token from somewhere in the settings) and a keyword `k`. When I want to search, I type `k giant isopod` and hit enter -- that takes me to the search results. Note that that also works in private browsing windows, whether you want it to or not. :-P So you never have to worry about whether you're signed in.

Keyword searches are cool because you can use them for any site that exposes a query through any part of the URL.
