I want to use fields of type `dense_vector` in an engine.  
It appears it is supported on `elastic search` but not on `app search` (Enterprise search).

The documentation at [Schema API | Elastic App Search Documentation [7.14] | Elastic](https://www.elastic.co/guide/en/app-search/7.14/schema.html) lists only text , number , date , geolocation as valid types.

Here is a link to a document that talks about the dense vector support in elastic search.

> **[Dense vector field type | Elasticsearch Guide \[7.14\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/dense-vector.html)**

Is there any way to use dense-vector fields in appsearch engine documents and use cosine similarity scores?

Hi Suresh, thanks for trying App Search.

`dense_vector` field types are not yet supported in App Search.

Not at this time, but that may change in the future.
