i might be wrong but i didn't think OP was suggesting to re-index the web. that's a totally different beast from finding an answer to a question/problem or learning a new topic.

depending on what i am looking for there are a few avenues i would explore if google wasn't available. github, gitlab, & stackoverflow/stackexchange for code related stuff.

wikipedia for general topics. youtube for how-tos. twitter for the news. newsletters and podcasts for links to new articles.

&c.
