For example I have following 2 documents:

{"id":"1", "title":"elasticsearch", " description":"elasticsearch" }

{"id":"1", "title":"elasticsearch", " description":"bing" }

And following query:  
{  
"query" : {  
"bool": {  
"should": [  
{  
"match": {  
"title": {  
"query": "elasticsearch"  
}  
}  
},  
{  
"match": {  
"description": {  
"query": "elasticsearch"  
}  
}  
}]  
}  
}  
}

The result score of documetn "1" is just the _SUM_ of the scores of 2 sub  
should clause, since both title and description contains "elasticsearch":

\_explanation:  
{  
value: 0.4339554  
_description: "sum of:_"  
details: [2]  
0:  
{  
value: 0.2169777  
description: "weight(title:google in 0) [PerFieldSimilarity], result of:"  
}  
1:  
{  
value: 0.2169777  
description: "weight(description:google in 0) [PerFieldSimilarity], result  
of:"  
}  
}

The result score of document "2", however, is different:

explanation:  
{  
value: 0.04500804  
_description: "product of:"_  
details: [2]  
0:  
{  
value: 0.09001608  
}  
1:  
{  
value: 0.5  
_description: "coord(1/2)"_  
}

The final score if NOT "_SUM of"_ but _"product of"_, I think it is because  
in document "2", the "description" field does not contains  
"elastticsearch", that is, half of all sub should clause match the query  
term, that is why \*coord(1/2) \*comes in explanation.

My question is, is it possible to change the score mode of SHOULD clause so  
that, the final score of SHOULD clause is always the \*SUM \*of sub clause,  
no matter whether the sub clause match the query term or not?

Have you tried the disable\_coord feature of bool queries?  
[https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-bool-query.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-bool-query.html)

It might give you what you need.
