Filter static value multiple parameters

General
1

Hi,

I would like to use multiple url parameters for one static filter option. I noticed that multiple values are separated with %2C. So I tried to use a value like this: term01%2Cterm02 and expected the url parameters to look like this:

?category=term01%2Cterm02

instead the url parameter is this:

?category=term01%26term02

Also it does not work like this.

How can I get this to work?
