rules.match.vars dynamic filtering on name

[sylflo]

I have a route with the Content Type application/x-www-form-urlencoded and send the following body in a POST request

'Filter.1.Name=Name1&Filter.1.Value.1=Value1&Filter.2.Name=hey&Filter.2.Value.1=hello&Filter.2.Value.2=plop'

I would like to know if it's possible to use rules.match.vars for this use case. I tried to set to do something like this, by hoping that "*" would be take as a wildcard but it's not working so far

[
      "post_arg_Filter.*.Name",
      "==",
      "toot"
    ]

So far, I understand this part of ApiSix uses this https://github.com/api7/lua-resty-expr#operator-list . So I don't know if it's possible to do what I want here
