Hi Vlad,

It is not "completely" wrong - any time that I have seen that advice it was also accompanied by a recommendation to *ALSO* make another TAG on the same expression *without* the filter.
And the filter was virtually always suggested for the PRIMARY key or a CANDIDATE key. That is, not willy-nilly for many TAGs.

Cheers,
