Like bug#14673 added `Buffer-menu-multi-occur' to invoke Occur
from multiple marked buffers, it would also make sense to invoke Occur
from other search types where the search space differs from the default
single-buffer search. Then typing `M-s o' in the minibuffer's isearch
will show occurrences from all minibuffer history elements, and
when typed in the comint's history isearch, will show occurrences
from all shell history elements:

That's an interesting feature... But with normal `C-s i foo M-s o', we
can then jump to the result, while we can't really do that there, can
we? So there's a bit of a disconnect between using an Occur buffer and
the minibuffer...

That was a year ago, and there was no response, so I'm guessing there
wasn't much interest in adding this feature, so I'm closing this bug
report. Please reopen if this is incorrect.
