{  
"error": {  
"root\_cause": [  
{  
"type": "illegal\_argument\_exception",  
"reason": "[field\_sort] unknown field [title], parser not found"  
}  
],  
"type": "illegal\_argument\_exception",  
"reason": "[field\_sort] unknown field [title], parser not found"  
},  
"status": 400  
}

we are getting response in Elasticsearch 2.4 when we moved version of jar to 5.6 we see above error reponse.

Thanks
