Maybe it would be good to show the message before the prompt and on its
own line? That way it could perhaps easily be made read-only etc.

It also seems to be a rather natural place to show it - at least if you
are used to command line tools.

I don't understand what do you propose.  Currently the error message
is already before the prompt and looks like:

It was me that did not understand, sorry. I suggested adding the messages to the prompt, but as Stefan pointed out this does not work if the minibuffer only has a single line available.

Reading the thread more carefully I see that you have found that the 2 seconds delay when using minibuffer-message can be very disturbing. How about redesigning that part, something like this:

- If there is an old minibuffer-message "active" then immediately remove this and put a copy in the *Message* buffer.
- Then display the new minibuffer-message.

Failing I-search backward: bar

but overwrites the minibuffer content.  With `minibuffer-message'
it looks like:

I-search backward: foo [Failing I-search backward: bar]

If necessary, we can make the error message shorter like:

I-search backward: foo [Failing: bar]

Looks good to me.

Anyway, to show the failed search string is more important than
the minibuffer content.

And the suggestion to make minibuffer-message fallback to just message if the minibuffer is not active seems useful.
