Yes, try (eldoc-show-in-mode-line "foo")

I don't use isearch, so i don't know what to display in mode-line, but i
imagine you can display something useful in mode-line, like a minimal
help depending of the context of your search.
I already use that in some places in ioccur and anything.
You can also in addition of a minimal help in mode-line display a
_full window_ with all the binding of isearch but without quitting isearch
like C-h m does actually.
It's not hard to do, just create a help function for isearch and bind it
in isearch map.

For example:
Try M-x anything-buffer+ then C-c ? to see what i mean.
