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'] = 1;   //当前只有一台ES，1就可以了
        $indexParams['body']['settings']['number_of_replicas'] = 0; //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' => 5 ); $params['index'] = 'myindex';  //索引名称 
        $params['type'] = 'mytype';   //类型名称 
        $params['id'] = '12345678';     //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'] = '123'; $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'] = 0; $searchParams['size'] = 100; $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'; $retDoc = $this->client->search($searchParams); echo '<pre>'; print_r($retDoc); //相当于sql语句： select * from hp_product where product_name like '茶' and product_id = 20 limit 200,10; // $searchParams['body']['query']['bool']['must'] = array( // array('match' => array('product_name' => '茶')), // array('match' => array('product_id' => 20)) // ); // $searchParams['size'] = 10; // $searchParams['from'] = 200; // 
        //  
        // 当于sql语句：select * from hp_product where product_name like '茶' or product_id = 20 limit 200,10; // $searchParams['body']['query']['bool']['should'] = array( // array('match' => array('product_name' => '茶')), // array('match' => array('product_id' => 20)) // ); //$searchParams['size'] = 10; //$searchParams['from'] = 200; //
        //
        // 当于sql语句： select * from hp_product where product_name like '茶' and product_id != 20 limit 200,10; // $searchParams['body']['query']['bool']['must_not'] = array( // array('match' => array('product_name' => '茶')), // array('match' => array('product_id' => 20)) // ); //$searchParams['size'] = 10; //$searchParams['from'] = 200; //
        //
        //当于sql语句：select * from hp_product where id>=20 and id<30 limit 200,10; // $searchParams['body']['query']['range'] = array( // 'id' => array('gte' => 20,'lt' => 30); // ); //$searchParams['size'] = 10; //$searchParams['from'] = 200; 
 } //获取文档
    public function get_document() { $getParams = array(); $getParams['index'] = 'myindex'; $getParams['type'] = 'mytype'; $getParams['id'] = '12344'; $retDoc = $this->client->get($getParams); print_r($retDoc); } } ?>
