Hi Team,

I have seen caps in field names while doing a search. Specially inside should block which contributes to score. I tried doing similar thing to see the effect but score remained same whatever number I gave after ^. Below is the sample query:

{  
"query": {  
"function\_score": {  
"score\_mode": "sum",  
"boost\_mode": "sum",  
"boost": 1,  
"query": {  
"bool": {  
"should": [  
{  
"constant\_score": {  
"filter": {  
"multi\_match": {  
"fields": [  
"firstName.analyzed^2"  
],  
"query": "\*John"  
}  
},  
"boost": 1.2  
}  
},  
{  
"constant\_score": {  
"filter": {  
"multi\_match": {  
"fields": [  
"lastName.analyzed^8"  
],  
"query": "\*Cena"  
}  
},  
"boost": 1.4  
}  
}  
]  
}  
}  
}  
}  
}

Here, firstName and lastName has ^with value of 2 and 8. Using explain api I checked document score with different values but it remained same.

So my query is why do we use ^ operator in search queries ? Does it have any impact on the result sets returned in terms of number or order.

Any hint or idea may help me in understanding this.

Thanks,

From a quick glance it is the use of the “constant\_score” wrapper that is making your boosts redundant.

I guess I am not clear with the use of constant\_score within functional score. Let me try some more things to exactly discuss the issue with you.

Thanks anyways for giving some hint.
