I actually make these whenever I get frustrated by Google a few times. I have "m" for MDN... It's not hard you just need to pick a keyword. How to modify the URL in the search string should be pretty obvious. I think you'll find you don't need them for every library. It's mostly general tools with large user bases, like Python, where people are trying to make a living shitting up the search results.
I also use the uBlacklist extension to hide W3Schools et al. https://chrome.google.com/webstore/detail/ublacklist/pncfbmi...
