## 📖 Documentation

This readme contains all the documentation you need to start using this Meilisearch SDK.

For general information on how to use Meilisearch—such as our API reference, tutorials, guides, and in-depth articles—refer to our [main documentation website](https://meilisearch.com/docs).

## 🔧 Installation

The package can be installed by adding `meilisearch_ex` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:finch, "~> 0.14.0"},
    {:meilisearch_ex, "~> 1.2.1"}
  ]
end
```

`meilisearch-ex` officially supports `elixir` versions >= 1.14

### Run Meilisearch

To use one of our SDKs, you must first have a running Meilisearch instance. Consult our documentation for [instructions on how to download and launch Meilisearch](https://www.meilisearch.com/docs/learn/getting_started/installation#installation).

## Usage

There is multiple ways to define and start the Meilisearch client:

```elixir
# Start finch with your app
Finch.start_link(name: :search_finch)

# Create a Meilisearch client whenever and wherever you need it.
[endpoint: "http://127.0.0.1:7700", key: "masterKey", finch: :search_finch]
|> Meilisearch.Client.new()
|> Meilisearch.Health.get()

# %Meilisearch.Health{status: "available"}
```

But you can also start a client alongside your application to access it whenever you need it.

```elixir
Finch.start_link(name: :search_finch)

Meilisearch.start_link(:main, [
  endpoint: "http://127.0.0.1:7700",
  key: "replace_me",
  finch: :search_finch
])

:main
|> Meilisearch.client()
|> Meilisearch.Health.get()

# %Meilisearch.Health{status: "available"}
```

Within a Phoenix app you would do like this:

```elixir
defmodule MyApp.Application do
  # ...

@impl true
  def start(_type, _args) do
    children = [
      # ...
      {Finch, name: :search_finch},
      {Meilisearch, name: :search_admin, endpoint: "http://127.0.0.1:7700", key: "key_admin", finch: :search_finch},
      {Meilisearch, name: :search_public, endpoint: "http://127.0.0.1:7700", key: "key_public", finch: :search_finch}
    ]

# ...
  end

# ...
end

defmodule MyApp.MyContext do
  def create_search_index() do
    :search_admin
    |> Meilisearch.client()
    |> Meilisearch.Index.create(%{uid: "items", primaryKey: "id"})
  end

def add_documents_to_search_index(documents) do
    :search_admin
    |> Meilisearch.client()
    |> Meilisearch.Document.create_or_replace("items", documents)
  end

def search_document(query) do
    :search_public
    |> Meilisearch.client()
    |> Meilisearch.Search.search("items", %{q: query})
  end
end
```

### Using another HTTP adapter

Given that the HTTP client is backed by Tesla behind the scene, you can freely use another adapter if it is more suitable for you.

```elixir
def deps do
  [
    {:hackney, "~> 1.18"},
    {:meilisearch_ex, "~> 1.2.1"}
  ]
end
```
```elixir

# Create a Meilisearch client whenever and wherever you need it.
[endpoint: "http://127.0.0.1:7700", key: "masterKey", adapter: Tesla.Adapter.Hackney]
|> Meilisearch.Client.new()
|> Meilisearch.Health.get()

# %Meilisearch.Health{status: "available"}
```

## 🎬 Getting started

### Add documents

```elixir
# Create the Meilisearch instance
Meilisearch.Client.new(endpoint: "http://localhost:7700", key: "masterKey")
# If the index 'movies' does not exist, Meilisearch creates it when you first add the documents.
|> Meilisearch.Document.create_or_replace(
  "movies",
  [
    %{id: 1, title: "Carol", genres: ["Romance", "Drama"]},
    %{id: 2, title: "Wonder Woman", genres: ["Action", "Adventure"]},
    %{id: 3, title: "Life of Pi", genres: ["Adventure", "Drama"]},
    %{id: 4, title: "Mad Max: Fury Road", genres: ["Adventure", "Science Fiction"]},
    %{id: 5, title: "Moana", genres: ["Fantasy", "Action"]},
    %{id: 6, title: "Philadelphia", genres: ["Drama"]}
  ]
)
# => {
#  :ok,
#  %{taskUid: 0, indexUid: "movies", status: :enqueued, type: :documentAdditionOrUpdate, enqueuedAt: ~U[..] }
# }
```

Tasks such as document addition always return a unique identifier. You can use this identifier `taskUid` to check the status (`enqueued`, `processing`, `succeeded` or `failed`) of a [task](https://www.meilisearch.com/docs/reference/api/tasks).

### Basic search

```elixir
# Meilisearch is typo-tolerant:
Meilisearch.Client.new(endpoint: "http://localhost:7700", key: "masterKey")
|> Meilisearch.Search.search("movies", q: "philoudelphia")
```

Output:

```elixir
{:ok, %{
  offset: 0,
  limit: 20,
  estimatedTotalHits: 1,
  processingTimeMs: 1,
  query: "philoudelphia",
  hits: [%{
    "id" => "6",
    "title" => "Philadelphia",
    "genres" => ["Drama"]
  }]
}}
```
