BusCar

A super simple Elasticsearch tool with its own DSL and Ecto-like usage.

Usage

Make the Repo

defmodule Example.Repo do
  use BusCar.Repo, otp_app: :some_example
end

Make a Mapping

defmodule Example.Doge do
  use BusCar.Document

  document "animal", "dog" do
    property :name, :string
    property :age,  :integer

    timestamps
  end

end

Get all the Models (aliased names see .iex.exs for example)

iex> Repo.all(Doge)
[
  %Example.Doge{_version: 1, age: 26, id: "33", inserted_at: "2016-09-26T02:34:20.187264Z", name: "Moe Moe", updated_at: "2016-09-26T02:34:20.187264Z"},
  %Example.Doge{_version: 1, age: 10, id: "AVdkWj0_-SwwFG-cHjcZ", inserted_at: "2016-09-26T02:36:58.044176Z", name: "Dora", updated_at: "2016-09-26T02:36:58.044176Z"}
]

Insert a few Models

iex> Repo.insert(%Doge{name: "Daisy May", age: 18})
%Example.Doge{_version: 1, age: 18, id: "AVdkXSuf-SwwFG-cHjcd", inserted_at: "2016-09-26T02:40:10.140185Z", name: "Daisy May", updated_at: "2016-09-26T02:40:10.140185Z"}

iex> Repo.insert(%Doge{id: 10, name: "Punky", age: 35})
%Example.Doge{_version: 1, age: 35, id: "10", inserted_at: "2016-09-26T02:50:21.290414Z", name: "Punky", updated_at: "2016-09-26T02:50:21.290414Z"}

Go Bananas (Young Adult Doges only)

iex> Repo.search(Doge, [:query, :bool, :must, :range, :age, :gte, 18, :lt, 30])
[
  %Example.Doge{_version: nil, age: 26, id: "33", inserted_at: "2016-09-26T02:34:20.187264Z", name: "Moe Moe", updated_at: "2016-09-26T02:34:20.187264Z"},
  %Example.Doge{_version: nil, age: 18, id: "AVdkXSuf-SwwFG-cHjcd", inserted_at: "2016-09-26T02:40:10.140185Z", name: "Daisy May", updated_at: "2016-09-26T02:40:10.140185Z"}
