Hi guys,  
Iam new to elasticsearch. I have indexed a small file. I get an error when i try to query it through an API as below:

"{  
"errors": [  
{  
"message": "index\_not\_found\_exception",  
"locations": [  
{  
"line": 2,  
"column": 3  
}  
],  
"path": [  
"gene"  
]  
}  
],  
"data": {  
"gene": null  
}  
}

I am not able to figure out of the file has a problem, its content or the API connection. Is there a way to figure this out?

Mamta

Which API are u using? How do you know indexing was successful? Can you share code you are using to query?

Also post output of

`curl http://localhost:9200/_cat/indices`
