A DSL-free Elasticsearch client for Elixir.
Even though the documentation is pretty scarce right now, we're working on improving it. If you want to help with that you're definitely welcome 🤗
This README contains most of the information you should need to get started, if you can't find what you're looking for, either look at the tests or file an issue!
Add elastix to your list of dependencies in mix.exs:
def deps do
[{:elastix, ">= 0.0.0"}]
endThen run mix deps.get to fetch the new dependency.
Elastix.Index.create("http://localhost:9200", "twitter", %{})elastic_url = "http://localhost:9200"
data = %{
user: "kimchy",
post_date: "2009-11-15T14:12:12",
message: "trying out Elastix"
}
mapping = %{
properties: %{
user: %{type: "text"},
post_date: %{type: "date"},
message: %{type: "text"}
}
}
Elastix.Mapping.put(elastic_url, "twitter", "tweet", mapping)
Elastix.Document.index(elastic_url, "twitter", "tweet", "42", data)
Elastix.Search.search(elastic_url, "twitter", ["tweet"], %{})
Elastix.Document.delete(elastic_url, "twitter", "tweet", "42")Bulk requests take as parameter a list of the lines you want to send to the _bulk endpoint.
You can also specify the following options:
indexthe index of the requesttypethe document type of the request. (you can't specifytypewithout specifyingindex)
lines = [
%{index: %{_id: "1"}},
%{field: "value1"},
%{index: %{_id: "2"}},
%{field: "value2"}
]
Elastix.Bulk.post(elastic_url, lines, index: "my_index", type: "my_type")
# You can also send raw data:
data = Enum.map(lines, fn line -> Poison.encode!(line) <> "\n" end)
Elastix.Bulk.post_raw(elastic_url, data, index: "my_index", type: "my_type")config :elastix,
shield: true,
username: "username",
password: "password",config :elastix,
json_options: [keys: :atoms!],
httpoison_options: [hackney: [pool: :elastix_pool]]Note that you can configure Elastix to use any JSON library, see the "Custom JSON codec" page for more info.
config :elastix,
custom_headers: {MyModule, :add_aws_signature, ["us-east"]}custom_headers must be a tuple of the type {Module, :function, [args]}, where :function is a function that should accept the request (a map of this type: %{method: String.t, headers: [], url: String.t, body: String.t}) as its first parameter and return a list of the headers you want to send:
defmodule MyModule do
def add_aws_signature(request, region) do
[{"Authorization", generate_aws_signature(request, region)} | request.headers]
end
defp generate_aws_signature(request, region) do
# See: https://github.com/bryanjos/aws_auth or similar
end
endYou need Elasticsearch running locally on port 9200. A quick way of doing so is via Docker:
$ docker run -p 9200:9200 -it --rm elasticsearch:5.1.2
Then clone the repo and fetch its dependencies:
$ git clone [email protected]:werbitzky/elastix.git
$ cd elastix
$ mix deps.get
$ mix test
