Module rs_es::query

Implementation of the ElasticSearch Query DSL.

ElasticSearch offers a rich DSL for searches. It is JSON based, and therefore very easy to use and composable if using from a dynamic language (e.g. Ruby); but Rust, being a staticly-typed language, things are different. The rs_es::query module defines a set of builder objects which can be similarly composed to the same ends.

For example:

use rs_es::query::Query;

let query = Query::build_bool()
    .with_must(vec![Query::build_term("field_a",
                                      "value").build(),
                    Query::build_range("field_b")
                          .with_gte(5)
                          .with_lt(10)
                          .build()])
    .build();
