Duck duck go is terrible. I give it a try frequently, and it is the default search provider on my phone, but most of the time I get useless results and have to either do it again with google or give up and try searching the history on my desktop for what I needed. I don't know why PLAIN TEXT SUBSTRING MATCHING is so flipping hard. Yes, I know spam exists, but I would prefer a dumb search to a smart but useless one.

Looking at my own webserver logs, I often wonder why ahrefs or majestic do not start a search engine effort. They crawl me as often as bing or google do, and could easily get a foothold with a "less is more" approach to search.
