使用可能值数组过滤结果

Question

我有以下映射：

    <tbody>   
        <form action="update_quantity.php" method="post" class="c-shop-form-1">
            <?php while ($row = mysqli_fetch_array($query)) { 

                   $id2=$row['id'];

                   echo "<tr><td>{$row['name']}</td>
                        <td>
                            <input type='text' class='form-control c-square c-theme' style='width: 90px;' placeholder='Quantity' name='Quantity' id='Quantity'>
                        </td>  

                        <td>
                            <input type='text' class='form-control c-square c-theme' style='width: 90px;' placeholder='Quantity' name='Quantity2' id='Quantity2'>
                        </td> 
                    </tr>";
            }?> 
            <tr>
                <td></td>
                <td></td>
                <td><button type="submit" name="RCV" id="RCV" value="submit" class="btn c-theme-btn c-btn-square center c-btn-bold c-btn-uppercase">Submit</button></td>
            </tr>
        </form>     
    </tbody>

并执行简单查询：

{
  cities: {
    mappings: {
      city: {
        properties: {
          id: {
            type: "long"
          },
          name: {
            type: "text",
            fields: {
              keyword: {
                type: "keyword",
                ignore_above: 256
              }
            }
          },
          population: {
            type: "long"
          },
        }
      }
    }
  }
}

所以我得到的结果是：

{
  query: {
    bool: {
      must_not: { match: { name: 'New York' } },
    },
  },
  size: 2,
}

如何限制此查询以匹配{ "took": 5, "timed_out": false, "_shards": { "total": 5, "successful": 5, "failed": 0 }, "hits": { "total": 10385, "max_score": 1, "hits": [ { "_index": "cities", "_type": "city", "_id": "14", "_score": 1, "_source": { "name": "Berlin", "id": 14, "population": 7293 } }, { "_index": "cities", "_type": "city", "_id": "19", "_score": 1, "_source": { "name": "Paris", "id": 19, "population": 25018 } } ] } } 在特定数组值中的文档，即name？

我正在寻找类似于SQL语句的东西：

['Berlin', 'Bonn', 'Munchen']

Answer 1

您可以使用terms query，因此您的查询应如下所示：

{
  query: {
    bool: {
      must: { terms: { 'name.keyword': ['Berlin', 'Bonn', 'Munchen'] } }
      must_not: { match: { name: 'New York' } },
    },
  },
  size: 2,
}

Answer 2

POST /cities/_search
{
  "query": {
    "bool" : {
      "must" : [
        { "match" : { "name" : "Berlin" } },
        { "match" : { "name" : "Munchen" } },
        { "match" : { "name" : "Bonn" } }
      ],
      "minimum_should_match" : 3
    }
  }
}

或

POST /cities/_search
{
  "query": {
    "bool" : {
      "must" : [
        { "term" : { "name.keyword" : "Berlin" } },
        { "term" : { "name.keyword" : "Munchen" } },
        { "term" : { "name.keyword" : "Bonn" } }
      ],
      "minimum_should_match" : 3
    }
  }
}
