Thanks, Erik. I've merged your pull request. So now it's very easy to
start using recoll with Emacs - outside of Emacs the only necessary
thing is:

    sudo apt-get install recoll

And inside Emacs it's:

    package-install counsel

I did look into the annotation switch. The thing is that it just shows
some database aggregates instead of the actual line context, like grep
does. With 30 candidates and no line context, a pure list of files looks
simpler than a list of files and a list of out-of-sequence words that
each file contains.
