安装elasticsearch的php类库

单独安装elasticsearch的php类库

composer require elasticsearch/elasticsearch

使用类库：

require_once(  './vendor/autoload.php');
$esclient = Elasticsearch\ClientBuilder::create()
              ->setHosts(["192.168.8.115:9200"])
              ->build();

**

laravel中安装elasticsearch

**
进入laravel框架后，执行：

composer require elasticsearch/elasticsearch

1.在创建的方法中，使用如下代码：

use Elasticsearch\ClientBuilder;
$esclient = ClientBuilder::create()
              ->setHosts(["192.168.8.115:9200"])    //IP:端口号
              ->build();

2.创建索引

$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'id' => '10',
    'body' => [
		'testField' => 'abc',
		'title'	=> '你好,从纵向即文档这个维度来看，每列代表文档包含了哪些单词，。'
		]
];
$res=$esclient->index($params);
echo '<pre/>';
print_r($res);

3.针对数据库中某一条记录创建/更新索引
读取到数据库的数据为 $data。 假设某条记录的值是$data[0] 并且是 对象格式 可以使用如下代码 如果是数组只需要修 $data[0]->id为 $data[0][‘id’]。

  $params = [
          'index' => 'my_index_user',
          'type' => 'my_type_user',
          'id' => $data[0]->id,
          ];
          unset($data[0]->id);
          foreach ($data[0] as $k => $v){
              $params['body'][$k] = $v;
          }
           $res=$esclient->index($params);
            print_r($res);

3-1.读取所有数据,循环构建数组并且在循环中请求

  foreach($data as $kk=>$vv){
            $params = [
                'index' => 'my_index_user',
                'type' => 'my_type_user',
                'id' => $data[$kk]->id,
            ];
            unset($data[$kk]->id);
            foreach ($data[$kk] as $k => $v){
                $params['body'][$k] = $v;
            }
            $res=$esclient->index($params);
            print_r($res);
        }

4.批量索引

 $params = [
            'index' => 'my_indexa',
            'type' => 'my_typea',
            'body' => [
                ['index' => [ '_id' => 1]],
                [
                    'testField' => 'abc',
                    'title' => '你好,从纵向即文档这个维度来看，每列代表文档包含了哪些单词，。',
                    'content' => '中国非常强大的哈哈哈,不错,及时这个时代的步伐,研究红色呢过名生命科学'
                ],
                ['index' => [ '_id' => 2]],
                [
                    'testField' => '青山绿水',
                    'title' => '无名英雄',
                    'content' => '力量是非常强大'
                ],
                ['index' => [ '_id' => 3]],
                [
                    'testField' => 'abc',
                    'title' => '代码的力量',
                    'content' => '天天上学'
                ]
            ]
        ];

$res=$esclient->bulk($params);
print_r($res);

4-1.读取所有数据,循环构建一个大数组,最后请求接口一次

 $params = [
                'index' => 'my_index_user1',
                'type' => 'my_type_user1'
            ];
        $addpar=[];
        foreach($data as $key=>$val){
            $params['body'][]= ['index' => [ '_id' => $val->id]];
            unset($val->id);
            foreach($val as $k=>$v){
                $addpar[$k]=$v;
            }
            $params['body'][]=$addpar;
        }
        $res = $esclient->bulk($params);
        print_r($res);

5.获取和删除

$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'id' => '10',
];
 $esclient->get($params);
 $esclient->delete($params);

6.单字段检索

$search_params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'body'=> [
		'query'	=> [
			'match'	=> [
				'testField'	=> 'abc'
				
			]
		]
	]
];  
$res=$esclient->search($search_params);
print_r($res);

7.多字段检索

$search_params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'body'=> [
		'query'	=> [
			'bool'	=> [
				'should'	=> [
					['match'	=> ['testField'	=> 'abc']],
					['match'	=> ['title'	=> '中']]
				]
			]
			
		]

	]
    
];
$res=$esclient->search($search_params);
print_r($res);
