I have a use case where the data is stored in multiple nested fields. As shown below:

{ "field1":  
{ "sub\_field1": "string",  
"sub\_field2":"string"  
},  
{ "sub\_field1" :"string",  
"sub\_field2":"string"  
}  
},  
{"field2":  
{ "new\_field1": "string",  
"new\_field2":"string"  
},  
{ "new\_field1" :"string",  
"new\_field2":"string"  
}  
}  
Now, for each "query\_str" I have to query all these nested fields and get the max (scores) w.r.t all these fields and I have to calculate the sum of all such query\_str

This problem can be broken down into two sub problems :

1. For each Function Score Query, I can have different functions such that, each function should point out to each nested path. This will look some thing like below:

{  
"query": {  
"function\_score": {  
"functions": [  
{ "query":{  
"nested": {  
"path": "field1",  
"query": {  
"filter": { "term": { "field1.sub\_field1": "query\_str" }},  
"weight": 1 }}}  
},  
{ "query":{  
"nested": {  
"path": "field2",  
"query": {  
"filter": { "term": { "field2.new\_field1": "query\_str" }},  
"weight": 1 }}}  
} ],  
"score\_mode":"max"  
}  
}  
}

1. Nested Score\_modes:- after the above query, I will get some thing like max (scores) for one query string "query\_str". Now, I need an addition of all such maximum scores for different query strings.

To summarize mathematically,

final\_score = Sum on all queries ( for each\_ query max ( score\_on\_field1, score\_on\_field2))
