Question

我正在使用ElasticSearch（在使用FosElasticaBundle的Symfony 4项目中），我不知道如何构建如下查询：

Match if value in list of values

我有一个字段"code"，如果此字段"code"的值为："first or "second" or "third"

，我只需要检索一个元素

我尝试了条款：

必须查询：没有检索到任何内容，也许必须是"first AND "second" AND "third"？
应该查询：即使我有另一个值而不是"first or "second" or "third"，一切都被检索到了，所以查询是没用的吗？

我尝试使用Match（应该，必须）或逐个使用......没有...

那么，我怎样才能在elasticsearch中做到这一点？谢谢！

PUT some-test

PUT /some-test/doc/1
{
  "foo": "first"
}

PUT /some-test/doc/2
{
  "foo": "second"
}

PUT /some-test/doc/3
{
  "foo": "fourth"
}

POST some-test/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "foo": "first second third"
          }
        }
      ]
    }
  }
}

给了我

{
  "took": 4,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "skipped": 0,
    "failed": 0
  },
  "hits": {
    "total": 2,
    "max_score": 0.2876821,
    "hits": [
      {
        "_index": "some-test",
        "_type": "doc",
        "_id": "2",
        "_score": 0.2876821,
        "_source": {
          "foo": "second"
        }
      },
      {
        "_index": "some-test",
        "_type": "doc",
        "_id": "1",
        "_score": 0.2876821,
        "_source": {
          "foo": "first"
        }
      }
    ]
  }
}

ElasticSearch匹配值列表中的值
