Hello,

I have a field indexed as a boolean. I wonder if there is a way to boost the document when this value is true and not boost it when the value is false.

I can't find a way to do it.

Thanks.

Welcome djean,  
I guess [function\_score](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-function-score-query.html) should work as your expected way.

Thank you [wangqinghuan](https://discuss.elastic.co/u/wangqinghuan) for your reply. You mean something like that:

```auto
     GET /_search
         {
         "query": {
             "function_score": {
               "query": { "match_all": {} },
               "functions": [
                   {
                       "filter": { "match": { "test": false} },
                       "weight": 23
                   },
                   {
                       "filter": { "match": { "test": true } },
                       "weight": 42
                   }
               ]
             }
         }
     }

```
