Hi,

I want to create FilterFunctionBuilder[] in order to create more than one ScoreFunctionBuilders, but when I try it in my project the only recognizable constructor is FunctionScoreQueryBuilder.FilterFunctionBuilder.

I want to create something like this using elasticsearch 6.0 java api:

{  
"query" : {  
"function\_score" : {  
"query" : {  
"bool" : {  
"must" : [  
----boolFilter----  
],  
"adjust\_pure\_negative" : true,  
"boost" : 1.0  
}  
},  
"functions" : [  
{  
"filter" : {  
"match\_all" : {  
"boost" : 1.0  
}  
},  
"script\_score" : {  
"script" : {  
"source" : "\_score \* (doc['field'].value!=0 ? 50000:1)",  
"lang" : "painless"  
}  
}  
},  
{  
"filter" : {  
"match\_all" : {  
"boost" : 1.0  
}  
},  
"script\_score" : {  
"script" : {  
"source" : "\_score \* (doc['field2'].value!=null ? 40000:1)",  
"lang" : "painless"  
}  
}  
}  
],  
}  
}  
}

Thank you in advance!
