Unable to retrieve data through Elasticsearch

Elastic Stack Elasticsearch
1

I'm able to perform all crud operations but whenever I tried to retrieve information through Elasticsearch I'm unable to do so.
GET
http://localhost:8080/topics/

{
"id": "1",
"name": "Java",
"desc": "Java Language Course"
}

The result isnot being displayed
POST
http://localhost:9200/topics/_search

{
"took": 35,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 0,
"max_score": null,
"hits":
}
}

GET http://localhost:8080/topics/

Wrong port?

What's the result of:

GET http://localhost:9200/_search
GET http://localhost:9200/_cat/indices?v

the port 8080 is working fine. I have tried changing the port as well. Produced the same results.

GET http://localhost:9200/_search
Result:
{
"took": 35,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 0,
"max_score": null,
"hits":
}
}

GET http://localhost:9200/_cat/indices?v

Elasticsearch does not listen to 2 REST ports. I'm unsure what service is running under 8080.

According to your last post, you did not index any document in elasticsearch. That's why you have no result.

Do you by any chance have 2 different Elasticsearch nodes/clusters that listen to ports 8080 and 9200 respectively?
