ESQueryBulid

以QueryBulider的形式来调用elasticsearch的PHP类，只是针对查询及结果做了封装

如果你使用过任何PHP框架，那么很快就可以入门，比较像sql语句

本类暂时只在elasticsearch 5.4版本上进行了验证，其他版本未做验证

举几个例子：

初始化

include 'ESQueryBuilder.php';

$ESQueryBuilder = new ESQueryBuilder('http://127.0.0.1:9200/test_index/test_type'); 
// IP:端口/索引(库)/类型(表) 且支持多hosts数组形式

单条查询

$ESQueryBuilder->select(['id', 'name', 'sex', 'age'])->andWhere('id', '1')->getSingleResult();

结果示例

{
    id: 1,
    name: "test",
    sex: "1",
    age: "18"
}

列表查询

$ESQueryBuilder->select(['id', 'name', 'sex', 'age'])->inWhere('sex', [1, 2])->limit(1, 10)->getLists();

结果示例

{
    "total": 100,
    "totalPages": 10,
    "pageSize": 10,
    "currentPage": 1,
    "lists": [
        {
            id: 1,
            name: "test",
            sex: "1",
            age: "18"
        }
    ]
}

聚合查询

$ESQueryBuilder->sum('age')->groupBy('sex')->getAggs();

获取原始查询语句

$ESQueryBuilder->getLists(true);

结果示例

{
    "_source": [
        "id",
        "name",
        "age",
        "sex"
    ],
    "query": {
        "bool": {
            "must": [
                {
                    "term": {
                        "id.keyword": {
                            "value": 1
                        }
                    }
                },
            ],
        }
    },
    "sort": [
        {
            "id": {
                "order": "desc"
            }
        }
    ],
    "size": 1,
    "from": 0
}

获取原始结果语句

$ESQueryBuilder->getLists(false, true);

结果示例

{
    "took": 2,
    "timed_out": false,
    "_shards": {
        "total": 5,
        "successful": 5,
        "failed": 0
    },
    "hits": {
        "total": 139,
        "max_score": null,
        "hits": [
            {
                "_index": "test_index",
                "_type": "test_type",
                "_id": "1",
                "_score": null,
                "_source": {
                    "id": "1",
                    "name": "test",
                    "sex": "1",
                    "age": "18"
                }
            }
        ]
    }
}
