Testing for an Empty String With the Following

Elastic Stack Elasticsearch
1

Hi,

Thanks for everyone's patience while I learn the elasticsearch query DSL.
I'm trying to get used to its verbosity.

How would I do a query like this, again in SQL parlance: select col1 from
mysource where col2 = "" and col3 in ["", "one", "two"] and col4 = "foo"

Hey,

not sure if you really want to test for an empty string, or maybe for an
empty field? There is a missing filter which you could potentially use for
that, see
