Is [https://www.elastic.co/guide/en/elasticsearch/guide/current/query-time-boosting.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/query-time-boosting.html) enough?

thanks for valuable reply

but it is not working in my case.

post requst [http://localhost:9200/hospitalsdev/hospitals/\_search?size=10000&from=0](http://localhost:9200/hospitalsdev/hospitals/_search?size=10000&from=0)

{  
"query": {  
"bool": {  
"should": [  
{ "match": { "providerName": {"query":"amit","operator":"and","boost": 6} }},  
{ "match": { "email": {"query":"amit","operator":"and","boost": 5} }},  
{ "match": { "website": {"query":"amit","operator":"and","boost": 4} }}

```
  ]
}

```

}  
}

this query means first give priority providerName than email than website.

it gives this result and not give priority to providerName . In first record providerName not have amit but it on first place.

Please format your code.

Why do you think that the first document is not more relevant than the 2nd and 3rd ones?

BTW you can use `explain` option to understand how the score is computed.
