ElasticSearch(六) Elasticsearch在Thinkphp5.0中的使用

首先下载需要引入的类库

链接：https://pan.baidu.com/s/1XEXviLoWM-ypwJ_B0jXqlg 密码：u54t    //Elasticsearch.zip类库压缩包地址

然后将压缩包解压到vendor目录下

<?php
namespace app\index\controller;
use think\Controller;
class Ec extends Controller
{
    public function _initialize()
    {

        Vendor('Elasticsearch.autoload');
        $params['hosts'] = array(
            '192.168.9.155:9200'
        );
        $this->client = new \Elasticsearch\Client($params);
    }
    public function index(){
        $this->search();
    }

    //创建索引
    //现在我们开始添加一个新的索引和一些自定义设置：
    public function create_index()
    {
        $indexParams['index'] = 'myindex';                         //索引名称
        $indexParams['type'] = 'mytype';                          //类型名称
        $indexParams['body']['settings']['number_of_shards'] = ;   //当前只有一台ES，1就可以了
        $indexParams['body']['settings']['number_of_replicas'] = ; //副本0，因为只有一台ES
        $this->client->create($indexParams);
    }
    //插入索引数据
    public function add_document()
    {
        $params = array();
        $params['body'] = array(
            'product_name' => '要插入的商品名称'，
            'prodcut_id' =>
        );
        $params['index'] = 'myindex';  //索引名称
        $params['type'] = 'mytype';   //类型名称
        $params['id'] = '';     //不指定id，系统会自动生成唯一id
        $ret = $this->client->index($params);
    }
    //删除索引
    //由于 elasticsearch 的动态性质，我们添加第一个文档的时候自动创建了索引和一些默认设置。让我们删除这个索引，因为我们以后想要指定自己的设置：
    public function delete_index()
    {
        $deleteParams['index'] = 'myindex';
        $this->client->indices()->delete($deleteParams);
    }
    //删除文档
    public function delete_document()
    {
        $deleteParams = array();
        $deleteParams['index'] = 'myindex';
        $deleteParams['type'] = 'mytype';
        $deleteParams['id'] = '';
        $retDelete = $this->client->delete($deleteParams);
    }
    //更改文档
    public function update_document()
    {
        $updateParams = array();
        $updateParams['index'] = 'myindex';
        $updateParams['type'] = 'mytype';
        $updateParams['id'] = 'my_id';
        $updateParams['body']['doc']['product_name']  = '新商品名';
       $response = $this->client->update($updateParams);

    }
    //查询
    public function search()
    {
        $searchParams['index'] = 'myindex';
        $searchParams['type'] = 'mytype';
        $searchParams['from'] = ;
        $searchParams['size'] = ;
        $searchParams['sort'] = array(
            '_score' => array(
                'order' => 'id'
            )
        );
        //相当于sql语句：  select * from hp_product where prodcut_name like '茶'  limit 0,100 order by id desc;
        $searchParams['body']['query']['match']['product_name'] = '茶';
