### Managing Chroma Collections (Elixir)

Source: https://github.com/0xalighieri/chroma/blob/main/README.md

Examples demonstrating how to use the `Chroma.Collection` module for basic collection operations: creating a new collection, getting or creating a collection, retrieving an existing collection, and deleting a collection. Metadata types can be specified during creation.

```Elixir
  {:ok, collection} = Chroma.Collection.create("my_collection", %{name: "string", age: "int"})
  {:ok, collection} = Chroma.Collection.get_or_create("my_collection", %{name: "string", age: "int"})
  {:ok, collection} = Chroma.Collection.get("my_collection")
  Chroma.Collection.delete("my_collection")
```

### Adding Chroma Dependency in mix.exs (Elixir)

Source: https://github.com/0xalighieri/chroma/blob/main/README.md

To install the Chroma client, add the `chroma` package as a dependency to your Elixir project's `mix.exs` file. Specify the desired version.

```Elixir
def deps do
  [
    {:chroma, "~> 0.1.2"}
  ]
end
```

--------------------------------

### Configuring Chroma Client (Elixir)

Source: https://github.com/0xalighieri/chroma/blob/main/README.md

Configure the Chroma client's connection details, such as the host, API base path, and API version, in your Elixir application's configuration file.

```Elixir
config :chroma, 
  host: "http://localhost:8000",
  api_base: "api",
  api_version: "v1"
```

--------------------------------

### Checking Chroma Database Version (Elixir)

Source: https://github.com/0xalighieri/chroma/blob/main/README.md

Verify the client's connection to the ChromaDB server by calling the `version` function from the `Chroma.Database` module.

```Elixir
Chroma.Database.version
```

--------------------------------

### Querying Chroma Collection (Elixir)

Source: https://github.com/0xalighieri/chroma/blob/main/README.md

Query a Chroma collection using the `query` function. Provide a list of query embeddings and optionally include `where` and `where_document` clauses to filter results based on metadata or document content.

```Elixir
  Chroma.Collection.query(collection, 
    %{
      embeddings: query_embeddings,
        query_embeddings: query_embeddings,
        where: %{"metadata_field": "is_equal_to_this"},
        where_document: %{"\$contains" => "search_string"}
    }
  )
```

--------------------------------

### Adding Data to Chroma Collection (Elixir)

Source: https://github.com/0xalighieri/chroma/blob/main/README.md

Add documents, their corresponding embeddings, metadata, and unique IDs to a specified Chroma collection using the `add` function. Embeddings are assumed to be generated externally.

```Elixir
  {:ok, collection} = Chroma.Collection.get_or_create("my_collection", %{type: "Text"})
  Chroma.Collection.add(collection, 
    %{
      embeddings: embeddings,
      documents: documents,
      metadata: metadata,
      ids: ids
    }
  )
```
