To resolve the 'Failed to parse mapping: Field [similarity] requires field [index] to be configured' error in Elasticsearch version 8.9.1, you need to ensure that the index parameter is set in the mapping for the dense_vector field. The error indicates that the similarity parameter requires the index parameter to be explicitly configured.

In your code, the mapping for the dense_vector field should be updated as follows:

Field.VECTOR.value: {
    "type": "dense_vector",
    "dims": dim,
    "similarity": "cosine",
    "index": True  # or False, depending on your needs
}

Make sure to update the mapping in the create_collection method where the index is created. This should resolve the error by ensuring that the index parameter is configured as required by Elasticsearch ^[1].
