laravel8 php7.3.4 mysql 5.7

centos8安装elasticsearch，出门左转找一下

安装扩展

composer require elasticsearch/elasticsearch

elasticsearch的中文开发文档

https://learnku.com/docs/elasticsearch-php/6.0

官方php客户端文档

注意：这里的只是类比，不是完全一样

你需要线上使用，请注意，深入理解elasticsearch的接口，因为php也是封装之后的使用，所以会有出入

$params = [
    'index' => 'my_index',  //索引名（相当于mysql的数据库）
    'body' => [
        'settings' => [
            'number_of_shards' => 5,  #分片数
        ],
        'mappings' => [ 
            'my_type' => [ //类型名（相当于mysql的表）
                '_all' => [
                    'enabled' => 'false'
                ],
                '_routing' => [
                    'required' => 'true'
                ],
                'properties' => [ //文档类型设置（相当于mysql的数据类型）
                    'name' => [
                        'type' => 'string',
                        'store' => 'true'
                    ],
                    'age' => [
                        'type' => 'integer'
                    ]
                ]
            ]
        ]
    ]
];

实例demo

测试数据

https://github.com/chinese-poetry/chinese-poetry

使用的是

chinese-poetryjsonpoet.song.0.json

写入数据库

CREATE TABLE `poet` (
 `id` bigint(20) NOT NULL AUTO_INCREMENT,
 `author` text CHARACTER SET utf8 COLLATE utf8_unicode_ci,
 `paragraphs` text CHARACTER SET utf8 COLLATE utf8_unicode_ci,
 `title` text CHARACTER SET utf8 COLLATE utf8_unicode_ci,
 PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=290 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci

写入的是时候会出现繁体问题

使用https://github.com/uutool/hanzi-convert

//简体转繁体：
$str = "好难";
HanziConvert::convert($str,true);
 
//繁体转简体
$str = "好難";
HanziConvert::convert($str);

虽然支持的不是很全，但是写入个100-200条足够测试了，或者可以吧你项目新闻类，或者产品类的数据库作为测试数据

 $data1 = file_get_contents('./poet.song.0.json');
        $dd = json_decode($data1, true);
        if (!empty($dd)) {
            foreach ($dd as $k => $v) {

                $Poet = new Poet();
                $Poet->author = HanziConvert::convert($v['author']);
                $Poet->paragraphs = HanziConvert::convert(implode(',', $v['paragraphs']));
                $Poet->title = HanziConvert::convert($v['title']);
                $Poet->save();
            }
        }
        die;

        $hosts = [
            '192.168.3.15:9200', // IP + Port
        ];
        $client = ClientBuilder::create()           // Instantiate a new ClientBuilder
                ->setHosts($hosts)      // Set the hosts
                ->build();              // Build the client object

        $Poet = Poet::get()->toArray();
        foreach ($Poet as $k => $v) {
            $params = [
                'index' => 'zx_index',
                'type' => 'zx_type',
                'id' => 'zx_' . $v['id'],
                'body' => [
                    'id' => $v['id'],
                    'author' => $v['author'],
                    'paragraphs' => $v['paragraphs'],
                    'title' => $v['title'],
                ],
            ];
            $response = $client->index($params);
        }

        $serparams = [
            'index' => 'zx_index',
            'type' => 'zx_type',
        ];

        $serparams['body']['query']['match']['paragraphs'] = '未离';
//        $serparams['body']['query']['match']['author'] = '宋太祖';
        $resech = $client->search($serparams);

        print_r($resech);

结果
