Thanks for updating the docs, see my comment inline.
And, yes, I think this documents the feature comprehensively and we can
close the issue!

Have actually tried the last example? I'm not sure the implicit 'OR'
applies when other expressions have been matched. So it may well be that
creator=3,1,-2 is a syntax error (and would return *all* issues) and you
really need the final 'OR' like in creator=3,1,-2,-4

Thanks!
