The approach is that you can construct a range query for your scenario and trigger that query through the NEST client's search method. Out of the box support will surely land in the package one day, but for now, there’s a simple and convenient way of implementing nested aggregations/facets with minimal efforts. Both provide a simple UI for generating queries - and you can convert the result to json and just use that in your code. By default, Elasticsearch changes the values of text fields as part of analysis. (Required, query object) It exposes the whole range of the DSL from Python either directly using defined classes or a queryset-like expressions. score?
