# Boosting 查询

**boosting**查询可以用来有效地降级能匹配给定查询的结果。 与**bool**查询中的“**NOT**”子句不同，这仍然会选择包含非预期条款的文档，但会降低其总分。

```
GET /_search
{
    "query": {
        "boosting" : {
            "positive" : {
                "term" : {
                    "field1" : "value1"
                }
            },
            "negative" : {
                 "term" : {
                     "field2" : "value2"
                }
            },
            "negative_boost" : 0.2
        }
    }
}
