  <P>
    这有很多，但你想研究“提升”。这可以在
    <a href="https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-boost.html" rel="nofollow noreferrer">
      映射级别
    </A>
     或者
    <a href="https://www.elastic.co/guide/en/elasticsearch/guide/current/_boosting_query_clauses.html" rel="nofollow noreferrer">
      查询级别
    </A>
    。
  </p>
  <P>
    映射示例：
  </p>
   <pre>
    <code>
      {
  "mappings": {
    "_doc": {
      "properties": {
        "location": {
          "type": "keyword",
          "boost": 2 <--- 2x boost to the final score
        }
      }
    }
  }
}

</code>
  </pre>
  <P>
    查询示例：
  </p>
   <pre>
    <code>

            "must": {

                    }
                }
            },
            "should": [
                { "term": {
                    "location": {
                        "value": "xxx",
                        "boost": 3 <--- 3x boost if the location matches
