Filter data and show another array based index

Hi,
I have a data source with two arrays.
First, I tried filtering the array and then showing another array-based filter result index, but this did not work.

As an example:

['big,'big','small','big]
['elephant','hipo','bird','lama']

My goal is to filter out the word 'small' but show the word 'bird'

Hi @alexmuller! Can you share a screenshot of where you are doing this filtering? Happy to take a look. Is this similar to your use case?
