You probably redirected the output of journactl.

By default journalctl sends its output to a pager. Most likely that
pager is of the less/more variety. And in such pagers, "/" is a
search-forward-from-point command, adhering to the convention you have
observed.

Also, 'more' or 'less' behave like 'cat' when you redirect their
output to something not a terminal (like to a file, or when it's piped
to 'grep', etc).[1]

That last bit probably has something to do with this:

Anyways, when the pager behaves like 'cat', the search functionality
will be absent, obviously.

enough to make it work.
