No - I haven't checked

🧑‍🔬 User Persona(s)

Web developer, eventually the code running in web browser for any anonymous user.

💪 Motivation

...so that a web user can access anonymously the content of the registry with the filtering features of opensearch.

📖 Additional Details

The registry-api will have an additional endpoint which will securely forward queries to OpenSearch and return the response to the users.

Acceptance Criteria

Given an opensearch POST query
When I perform this query through the registry-api
Then I expect to get the opensearch result

Example POST query:

{
  "from": 0,
  "size": 9999,
  "query": {
    "wildcard": {
      "lid": {
        "value": "urn:*:investigation:*"
      }
    }
  }
}

TO BE DONE: add an example of query which would be rejected.
