hello,i tried adding to my code an ES query using Java API but i failed because of the lack of documentation and i would use some help. Here's the query i need to transform using Java API :  
"{  
"query":{  
"has\_child": {  
"type": "data",  
"score\_type" : "avg",  
"query" : {  
"query\_string": {  
"query": " abcdef" } } } }}"
