OpenSearch

Here is the data I’ve added in OpenSearch index

{
  "_index": "python-demo-index",
  "_type": "_doc",
  "_id": "8sdf67a84f-1dsdf",
  "_version": 1,
  "_score": 0,

I want to search by codes [i.e. NLP>Question>list of obj >.codes]

What I did previously is as below.

query = {
    "query": {
        "simple_query_string": {
            "query": "LP156192-9* | 8461-6",
            "fields": ["NLP.Question"]
        },
    },
}

search_response = client.search(
        body=query,
        index="python-demo-index",
        size=100,
        request_timeout=15
    )

But above code returns empty results?
can you help me with writing search query in python?
