Matrix, show all rows with same index but filter by value of a row

[ireferpesa]

I hope I am explaining myself well.
I'm racking my brain to figure out how to do this.
I have a table of events, to which I added an index, from this I created a revered table with the parameters of each event.
So far so good.
But now I need to get the id according to the value of one of the parameters.
I manage to do it, but then it only shows me that parameter, when I want to show them all.

I don't know if I made myself understood, so some screenshots for you to understand me.

These are the relationships

 

This is an example of parameters

And here's what I get when I filter by the value of one of the parameters

what I need is to look for the value of the parameter, but not to get just that value. If I look for x, I get the id that contains x in one of its rows.

no one knows how to do it?
