A high level library, giving a strongly typed DSL that maps one to one with the official Elasticsearch query DSL.
- Strongly typed queries
- Strongly typed aggregations
- Strongly typed completions
- Response structures
- Automatically skips empty queries making DSL pleasant to use
- Crate doesn't depend on elasticsearch-rs and can be used as a standalone library with any HTTP client to call Elasticsearch
Add elasticsearch-dsl crate and version to Cargo.toml
[dependencies]
elasticsearch-dsl = "0.4"Documentation for the library is available on docs.rs
