I have remembered that is possible make it shorter because you don't need
to know the output, you just need know if there is only one at least. The
then operator is unnecesary but we need change the last operator in the*
Filter Run*. We can do someting like this
{{{ [all[tiddlers]contains:tags[HelloThere]*limit[1]*] }}}
