Elastix

A simple Elastic REST client written in Elixir.

Preface

• Official Elastic Website
• and latest docs

This library talks to the Elastic(search) server through the HTTP/REST/JSON API. Its methods almost always return a HTTPoison request object.

When needed, the payload can be provided as an Elixir Map, which is internally converted to JSON. The library does not assume anything else regarding the payload and also does not (and will never) provide a magic DSL to generate the payload. That way users can directly manipulate the API data, that is sent to the Elastic server.

Overview

Elastix has 3 main modules and one utility module, that can be used, if the call/feature you want is not implemented (yet). However – please open issues or provide pull requests so I can improve the software for everybody. The modules are:

• Elastix.Index corresponding to: this official API Documentation
• Elastix.Document corresponding to: this official API Documentation
• Elastix.Search corresponding to: this official API Documentation
• and Elastix.HTTP – a thin HTTPoison wrapper

I will try and provide documentation and examples for all of them with time, for now just consult the source code.

Simple Example

start elastix application dependencies (or define it as an application dependency in mix.exs):

Elastix.start()

create the Elastic index

Elastix.Index.create("http://127.0.0.1:9200", "sample_index_name", %{})

assuming you have a model product create a document, search, or delete

# Elastic Server URL
elastic_url = "http://127.0.0.1:9200"

# Elastic Index Name
index_name = "shop_api_production"

# Elastic Document Type
doc_type = "product"

index_data = %{
  name: product.name,
  item_number: product.item_number,
  inserted_at: product.inserted_at,
  updated_at: product.updated_at
}

# add some search params according to Elastic JSON API
search_payload = %{}

# which document types should be included in the search?
search_in = [doc_type]

Elastix.Document.index(elastic_url, index_name, doc_type, product.id, index_data)
Elastix.Search.search(elastic_url, index_name, search_in, search_payload)
Elastix.Document.delete(elastic_url, index_name, doc_type, product.id)
