What did you do?
I searched for "rand".
What did you see happen?
The top search results were the standard library's math/rand and crypto/rand packages. The math/rand/v2 package, which is what I mean by "rand" in most new code I write today, does not appear in the list of search results. The only indication of math/rand/v2 is some small, easy-to-miss text below the math/rand search result which says:
Related packages in the standard library: math/rand/v2
What did you expect to see?
I think that if I search for "rand", math/rand/v2 ought to be very highly ranked in the search results; ideally, it would appear above math/rand. v2 is what people ought to be using for new code and we should nudge people in that direction. In any case, it should certainly appear near the top of the list.
I think this is just a case where pkgsite isn't keeping up with the v2 evolution happening in the standard library. As we get more v2 packages, the issue will get worse.
This is essentially the standard library equivalent of an issue I filed for third-party modules a few years back: #36969.
There's also a related, thornier issue: if I search for "math/rand", it takes me directly to https://pkg.go.dev/math/rand -- perhaps that ought to go to a search result page now that includes math/rand and math/rand/v2.
