<span class="quote">> The logical relation between criteria can be defined as logical AND (conjunction).
> In other words, if and only if all given criteria are met, a value from the
> corresponding cell of the given Func_Range is taken into calculation.</span >

There you may also find something to resolve your "additional" confusion:

<span class="quote">> Regex expressions should be like any other software, "*" alone doesn't mean
> anything, it should have something before it, for example:
> .*
> a*
> [1-9]*
> etc</span >

What you see are *not* "regular expressions". By default, wildcards are enabled
in Options/Calc/Caclulate. They have different simplified syntax.
