Hello. I need to implement some kind of similarity comparison.  
For example, lest assume that I have book object (with Author -boost 2, and  
number of pages - 1). How can I force that other book with this same data  
(author + number of pages\_ will return score as a 2+1 ?  
I really dont want to use any complex mathematical function. Just add a  
boost params, when its match.  
In other word max result should be sum of boost of individual fields

My query"  
{  
"query": {  
"filtered": {  
"query": {  
"bool": {  
"should": [  
{  
"match": {  
"season": {  
"query": 1,  
"boost": 5  
}  
}  
},  
{  
"match": {  
"appliance": {  
"query": 1,  
"boost": 2  
}  
}  
}  
]  
}  
},  
"filter": []  
}  
},  
"min\_score": 0  
}  
Max score is 1.2998674 But it should be 7
