I tried searching on my windows 10, here is what happened when i tried to search “how to make a multiplayer”:

Need help fixing search. Its not my laptop only i think i tried my other laptop and the same thing happened.

Look, as people have said on dozens upon dozens of posts about this, the serach function is broken, likely do to the faulty cookies or a server issue. This has been happening for quite some time now. Go to this thread instead of making another duplicate.

As @GameCatastrophe0927 helpfully stated, Scratch's search engine is currently broken, and all we can do is wait for it to be fixed.
Unfortunately, no one knows when this will be fixed or how to fix it.
This affects everyone on Scratch, so the Scratch Team is aware of the situation.

For now, you can type "site:scratch.mit.edu (search query)" into a search engine like Google to work around this bug.
You should also discuss the bug here: https://scratch.mit.edu/discuss/topic/790866/

This also affects the Explore page, since that's internally based on Scratch's search engine.
