Split and filter query

Hello, I have a problem

I get multiple values from a text field, the values are separated by a semicolon. until then no worries even if I had to do a split and fill in several variables to filter my query. my problem is that if I have less value than variables the filter no longer works because I think it considers empty as a value

How to do ?

Place each condition in a separate group and you can add a condition to each group by clicking on the question mark which will enable/ disable that condition.

You will probably need to check if each {{eanx}} value exists (is not null)

Thanks
