I am not sure I understand your context or goal in searching ;/

I.e., what did you briefly look for on the internet?
Did you search for an instance of "<https://issues.guix.gnu.org/45314>"
hoping to find discussion of it elsehere than at the URL itself?

What were you referring to with the "this" in
"...this is the kind of thing that seems difficult to search for." ?

If you were looking for alternate site discussion of bug#45314, duckduckgo
seems to respond better without the '#' and narrowed by a last search term
specifying the year, like
    duckduckgo "bug 45314" 2020
(don't leave out the quotes, and don't put the year inside them)

NB: there are lots of bug trackers out there, so you will probably
want to Ctl-f to ask your browser to walk through all the 45314's just by 
hitting Enter
after that (firefox example).

Not so many hits for 2021 yet, so I can show the result: (2 irrelevant hits :)

If your context is in emacs editing a git commit, and you just want an easy 
command to insert
a line like
    Fixes <https://issues.guix.gnu.org/45314>.
... I'm sure you can handle that yourself if you want to, hence my confusion 
about what you were up to ;)

But maybe you are lazy like me, and wanted to see what was available. For me, 
that brings up the question
of what form of solution would be most helpful to the most people if I offered 
one. E.g., I could

1. point you to the others' elisp solutions,
2. offer a bash script that formats the line based on clipboard-captured number 
(e.g., using xclip or wl-paste)
   which you can easily invoke from emacs by "Esc 1 Esc ! bash-script"
3. offer a guile script to do the same
4. offer a bash script that will compile and link a C program (source and 
commands all in script) that will do the same,
   assuming you have a usual x86_64 tool chain at hand, or
5. write it in some other interesting language (rash? :)

I am not sure having the solution be dependent on emacs' (or any limiting 
entity's) internals
is the most generally useful, but it's something I think about.

I'd be interested in what you all think, though maybe it ought to be a new 
thread ;)
