Hi @UMUT_CAN_ARGUN ,

Could you share how the index generated in Elasticsearch looks?  
Using Kibana Dev Tools:

1. Open Kibana and navigate to Dev Tools.
2. Use the following command to get the mapping of your index:

```json
GET /your-index-name/_mapping

```

Replace `your-index-name` with the actual name of your index.
