如何引入

引入步骤


public function getList($index, $keywords, $limit = 10, $page = 1, $sort_field='sort',$sort_value='desc')
{  
$offset = ((int)$page - 1) * (int)$limit;

    $params = [
        'index' => $this->_index_prefix . $index,
        'body' => [
            'query' => [
                'match' => [
                    'goods_name' => trim($keywords)
                ],
            ],
//highlight 声明高亮
//pre_tags 字符前
//post_tags 字符后
//fields  高亮字段  参数为数组 KEY 为字段名 VALUE  必须为obj 否则不生效

            'highlight' => [
                'pre_tags' => "

",
                'post_tags' => "

",
                'fields' => [
                    'goods_name' => (object)[]
                ]
            ],
            'sort' => [[$sort_field => ['order' => $sort_value]]],
            'from' => $offset,
            'size' => $limit
        ]
    ];

    if (empty($keywords)) {
        //如果没有搜索关键字 就删除query
        unset($params['body']['query']);
        unset($params['body']['highlight']);
    }
    $response = $this->_client->search($params);

    //$response['hits']['hits']是具体的数据列表
    return $response;
}

public function getNewGoodsEsList($param)

        $goods_name = $value['_source']['goods_name'];
        if(isset($value['highlight']['goods_name'][0])){
            $goods_name = $value['highlight']['goods_name'][0];

        'page'=>$param['page'],//当前页
        'last_page'=>ceil($result['hits']['total']['value']/$param['list_rows']),//总页数
