I have a search phrase with 2 parameters. After running it, I meant to launch the same one but with a different first parameter. As the search phrase still is displayed, I meant to modify the first parameter. For this, I first deleted the previous value.

This triggered an error (see screenshot) because it is trying to get suggestions on a empty string. a little exception to deal with ? because ctrl-R is the only way I found to get me out of this ...
