I am using elasticsearch primarily for aggregations, then eventually i came across setting the query size to zero, according to my understanding this helps in two ways :

1. payload size is reduced
2. and when we use query in filter context with size set to zero, elasticsearch internally caches the results .

I use python client to query my cluster. my doubt is,  
will setting size=0 in es.search(index=index, body=query, size=0) automatically override the json query and enable cache
