```

Have been able to reach to this point

FunctionScoreQueryBuilder functionScoreQueryBuilder = QueryBuilders  
.functionScoreQuery(queryBuilder)  
.setMinScore(0f)  
.maxBoost(50f)  
.scoreMode("max")  
.boostMode(CombineFunction.REPLACE);

But not sure about how to add the functions and filters ☹
