Deduplicating using nested query

Elastic Stack Elasticsearch
1

I have a simple problem where it would be useful to a query like: get me
everything that matches except if field foo is in results of
.

The simple solution is to first do query2, fetch the foo field for all the
results (potentially thousands), stuff it in some hash and generate a
gigantic set with all the values of the foo field and turn that into a bool
filter with a lot of term queries in the not that gets added to query1.

Since I need to support paging through the results, I can't get away with
simply tossing deduplicating the result set in memory.

Is there a more elegant way to do this in elasticsearch?

Don't know for sure, but did you try using a filter query ?
