[rogpeppe]

What is the URL of the page with the issue?

https://pkg.go.dev/search?q=os

What is your user agent?

What did you do?

Search for a standard library package.

What did you expect to see?

The standard library package as the top result.

What did you see instead?

Some other random packages that don't even have the name os.

Update: it seems to be working again now. But the above makes me feel like I can't trust it. Here are the new results:

I also observed some breakage on stdlib packages a few hours ago. Everyone of them had:

Imported by: 0

but if you clicked on it it would show thousands of importers (as you would expect for a stdlib package).

Now it seems to be fixed.

I'm seeing this right now.

I am experiencing the exact same thing as @cespare. I can only get to stdlib stuff if i give it the exact name of the package, like net/http for example while searching just http it's nearly impossible to find the stdlib one in the results.

It's working for me now, but I guess before closing it it would be good to hear confirmation of a fix from the team since it apparently has been toggling between these states over time.

I can confirm that https://pkg.go.dev/search?q=x509 works fine now (the problem reported in #47561, which was duped to this one)
