match-all and match-any option for collection may be redundant.

[Piroooh]

I'm reading the manual and in section 9.2 the option match-all and match-any are described. I think one option, let be match-all, set to true or false is sufficient to filter the exercises with corresponding tags.

Are not those two options redundant ? In particular, when the two options are set to true, i'm not sure which exercises should be printed.

Anyway, thanks for the package for 5 years now.
