I agree with OP here, these results are not great.

OP searched for the redis docker image, not a tutorial on how to use it, not a tutorial on why redis should be run in docker, and did not search for redis docker docs. While these are relevant, they should be further down, not the top result. DDG gets this right, and I’m pretty sure other search engines do too.

For a total newbie, these results are probably OK, but for a technical person who knows what they want literally as they type it, Google’s results are (excuse my french) simply shit. DDG is miles better at handling this stuff, and they don’t need your personal data to do it well either.

Edit: Just went and searched “redis docker image” in a private tab on Google, and the docker hub image for Redis is not even shown on the first page of results
