Module can not index vectors

Remarks

1 this is dependant on a module that provides the embeddings. And that embedding plugin should have

  /**
   * {@inheritdoc}
   */
  public static function getAzureDataType(): string {
    return 'Collection(Edm.Single)';
  }

  /**
   * {@inheritdoc}
   */
  public static function isCollection(): bool {
    return TRUE;
  }

I've tested this with search_api_ai and it's embedding plugin and this works.

2 we're not consuming the vectors in this system
but that is not the goal.

The algorithm is not configurable yet.
Currently we're hardcoded using

        'name' => 'drupal-vector-config-1',
        'kind' => 'hnsw',
        'hnswParameters' => [
          'm' => 4,
          'efConstruction' => 400,
          'efSearch' => 500,
          'metric' => 'cosine',
        ],

Thanks for the report and the MR!

We have vector fields on the roadmap in a later satge
The MR is currently not complete/ready for merge, but we'll see how we can integrate it in a generic yet flexible fashion.
