Hello!

At this point in my app I need to solve scoring implementation task. What I  
need to achieve is that - if term is found in \*Surname \*field, it can get  
custom boost that is taken from _scoreBoostForSurname_ otherwise (if term  
found in _Name_ then _scoreBoostForSurname_ value is not used)  
Lets assume I have simple three documents:  
{  
"thisID": "1",  
"name": "Elastic",  
"surname": "Search",  
"scoreBoosterForSurname": "0"  
}  
{  
"thisID": "2",  
"name": "Search",  
"surname": "Elastic",  
"scoreBoosterForSurname": "10"  
}  
{  
"thisID": "3",  
"name": "Search",  
"surname": "Elastic",  
"scoreBoosterForSurname": "5"  
}  
And now lets assume I'm querying these documents.  
'  
{  
query: {bool: {must: [{query\_string: {  
query: "Elastic",  
default\_operator: "AND",  
analyze\_wildcard: true,  
fields: [  
"name",  
"surname",  
]  
}}]}}  
}  
'  
What I prefer is that if ordered by score results are ordered and returned  
to me in this order 2,3,1 (values from \*thisID \*field)

So what I assume I need here is not custom score, but custom field  
boosting. Is it really achievable at the moment in Elastic Search? Or is  
there something about custom scoring or even Elastics scoring I don't know  
yet?

I checked on nested objects, but does help to solve my task as well as  
index with child elements as child elements are not included in final  
result when querying parent.

The other options I consider is to use custom score with duplicating user  
entries (documents) and then removing duplicated results at my application  
side.

I think you can do it by combining dis\_max with custom\_score query:

{  
"query": {  
"dis\_max": {  
"queries": [{  
"query\_string": {  
"query": "Elastic",  
"default\_operator": "AND",  
"analyze\_wildcard": true,  
"default\_field": "name"  
}  
},{  
"custom\_score": {  
"query": {  
"query\_string": {  
"query": "Elastic",  
"default\_operator": "AND",  
"analyze\_wildcard": true,  
"default\_field": "surname"  
}  
},  
"script" : "\_score \* doc['scoreBoosterForSurname'].value"  
}  
}  
]  
}  
}  
}

Here is a full example: [custom\_boost.sh · GitHub](https://gist.github.com/3990458)

Ok, thank you for your answer. I will see how it works and then give a  
feedback on this.

Have a great day!

Yes, this is exactly what I needed. Tested it with more complex queries and  
got the result desired.  
Once again thank you for your response.
