I have a data structure where certain fields are nested objects. For example, in my 'events' engine, the 'event\_permission' field is an array of objects, with each object containing a 'user\_id'.

I'm using @elastic/enterprise-search for nodejs. How can I filter by user\_id in the event\_permission array without denormalizitng the data?
