'Vector Search' not working in Elastic Search version 8.9.0

I'm trying to use the 'Vector Search' feature of elastic search which is available from version 8.0. I'm using the latest version 8.9.0, but I'm getting the error: unknown field [vector_search]

The query:

{
  "query": {
    "vector_search": {
      "query": "small forward",
      "fields": ["position"],
      "k": 10
    }
  }
}

Why is the query parameter "vector_search" not being recognized?

Not exactly related to Elastic Search but Astra Vector Search is Lucene based and queries are pretty straightforward. This is powered by scalability and performance of Apache Cassandra. See a quick intro doc https://docs.datastax.com/en/astra-serverless/docs/vector-search/cql.html

Here is a sample query

SELECT * FROM vsearch.products 
ORDER BY item_vector ANN OF [0.15, 0.1, 0.1, 0.35, 0.55]
LIMIT 1;
