MySQL查询到ElasticSearch

Question

我正在尝试将MYSQL查询转换为Elasticsearch。该查询包括在不同字段上的多个条件。让我解释一下我要达到的目标。我的MySQL查询是

Select * from data_fl where city IN 'miami,miamibeach,etc' AND phone!=0 AND (name like '%abc%' OR address like '%abc%' OR zip_code like '%abc%' OR phone Like '%abc')

如何在Elasticsearch中复制此查询。我的尝试是

$params = [
                              'index'=>'us_data_'.strtolower($state_code),
                              'body'  => [
                                  'query' => [
                                    'bool'=>[
                                        'filter'=>[
                                            'term'=>['city_code'=>$city_name]
                                        ],

                                      'should' => [
                                        'query_string'=>[
                                          'query'=>"*".$service."*",
                                          'fields'=>['name','contact_no','zip_code','city_code'],
                                        ]
                                      ]
                                    ]
                                  ]
                              ]
                    ];

但这不会返回任何内容。我正在使用Elasticsearch 7.6并尝试在Kibana上使用curl复制此查询，但答案仍然相同。

期待帮助

根据要求，索引的映射是

您正在使事情变得复杂，并试图在Elasticsearch中适应MySQL概念。在这种情况下，您需要正确定义索引映射（根据搜索要求来字段数据类型及其分析器），并相应地构建查询。

我已经获取了您的示例，并且没有更改索引映射和示例文档，但是更改了搜索查询以显示如何处理现有数据和需求（可能无法在所有情况下都有效，但是您有所了解）搜索。

搜索查询

{
    "query": {
        "multi_match": { --> note and read about multi_match query
            "query": "36695",
            "fields": [
                "address",
                "city_code", --> add more fields if you need to be
                "zip_code",
                "contact_no"
            ]
        }
    }
}

搜索结果将带您的示例文档：

 "hits": [
            {
                "_index": "so_mysql_dsl",
                "_type": "_doc",
                "_id": "1",
                "_score": 0.2876821,
                "_source": {

                    "name": "Port City Realty",
