What did you do?

Visited either of the search results pages above.

What did you expect to see?

For https://pkg.go.dev/search?q=goproxytes I would expect to see https://pkg.go.dev/github.com/rogpeppe/go-internal/goproxytest?tab=doc in the results.

For https://pkg.go.dev/search?q=sh I would expect to see:

What did you see instead?

For https://pkg.go.dev/search?q=goproxytes, zero results.

For https://pkg.go.dev/search?q=sh a number of results which I would consider "further away" than https://pkg.go.dev/mvdan.cc/sh/v3/syntax?tab=doc

FYI @mvdan

This is helpful, thanks! We are still tuning our search algorithm, so it's useful to know of these unexpected search results.

It sounds like there are a couple of suggestions here:

  • Support fuzzy matching (in the case of goproxytes)
  • Support searching by packages and modules.
    • For this suggestion, are you expecting to see links to both package and modules in the search results? Or a filter to search by modules instead of packages as @mvdan mentioned in #36814?
  • Rank the newest version of a module in a series of modules, higher than older ones (i.e. mvdan.cc/sh/v3/syntax should be high up in the search results)

Also in the case of searching for sh, I'm seeing mvdan.cc/sh/syntaxas the third result, and mvdan.cc/sh/interp as the fourth. Are those results ones that you would expect?

Regarding "Support searching by packages and modules"

For this suggestion, are you expecting to see links to both package and modules in the search results?

Yes. I think both should be returned, and there be some indicator (icon/colour/etc) that distinguishes a package vs a module.

Or a filter to search by modules instead of packages as @mvdan mentioned in #36814?

My sense is that it should be possible to add something like is:package or is:module to further constrain the search query but that the default should return both packages and modules.

Ranking

Rank the newest version of a module in a series of modules, higher than older ones (i.e. mvdan.cc/sh/v3/syntax should be high up in the search results)

As a broad heuristic to feed into the overall ranking algorithm, this feels sensible.

Also in the case of searching for sh, I'm seeing mvdan.cc/sh/syntax as the third result, and mvdan.cc/sh/interp as the fourth. Are those results ones that you would expect?

@mvdan will confirm, but, given the previous point, I would have expected to see mvdan.cc/sh/v3/syntax above mvdan.cc/sh/syntax, i.e. the later module version's packages ranking higher than the earlier

Whilst we are here, searching for mvdan.cc/sh/v3 seems to rank non-v3 packages above v3 packages:

Another unfortunate query is https://pkg.go.dev/search?q=gio, where I would expect the gioui.org module and packages to come near the top. However, the first appearance is on page 3, for the gioui.org/ui package:

https://pkg.go.dev/search?page=3&q=gio

linking to

https://pkg.go.dev/gioui.org/ui

which doesn't even exist anymore (I removed /ui/ from gioui.org packages a while back).
