Elastic Search - OR filter with boolean and ids

Question

I'm trying to search through items, where some of them might be private.

If a item is private, only friends of item owner (array item.friends) may see the item. If it's not private, everyone can see it.

So my logic is: If item is not is_private (is_private=0) OR user id (4 in my example) is in array item.friends, user can see the item.

Still i get no results. Every item is now set to is_private=1, so I guess something is wrong with my ids filter.

Any suggestions?

The "ids" filter probably does not mean what you think it means: it filters on the document ID (and, optionally, on the document type.)
