I think this relies on this being interpreted as a PCRE regex, which hasn't been the case for a while, since some server-side changes.

It looks like this is broken again. package-grep does work:

Thanks for pointing this out.

$ q=https://cygwin.com/cgi-bin2/package-grep.cgi
$ curl -s "$q"'?text=1&arch=x86_64&grep=mingw32-g%2B%2B' | awk 'NR>1{$0=$1}1'
Found 4 matches for mingw32-g++

mingw64-x86_64-gcc-g++-5.4.0-2
mingw64-x86_64-gcc-g++-5.4.0-3

but it seems no incantation will make cygcheck work:
[...]

    $ cygcheck -p mingw32-g++
    Found 0 matches for mingw32-g

It looks like the underlying bug here is that 'cygcheck -p' doesn't encode '+', but the package-grep-cgi script is expecting the query part of the URL to be application/x-www-form-urlencoded (as is the case with the web form interface to this search), where '+' is the encoding for a ' '...

I added a workaround to the script so that corresponding decoding ('+' -> ' ') is skipped if it looks like a cygcheck request ('text=1'), so this should be working again

$ cygcheck -p mingw32-g++
