laravel8 php7.3.4 mysql 5.7

centos8安裝elasticsearch，出門左轉找一下

安裝擴展

composer require elasticsearch/elasticsearch

elasticsearch的中文開發文檔

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

官方php客戶端文檔

Elasticsearch 權威指南

注意：這里的只是類比，不是完全一樣

你需要線上使用，請注意，深入理解elasticsearch的接口，因為php也是封裝之后的使用，所以會有出入

$params = [
    'index' => 'my_index',  //索引名（相當於mysql的數據庫）
    'body' => [
        'settings' => [
            'number_of_shards' => 5,  #分片數
        ],
        'mappings' => [ 
            'my_type' => [ //類型名（相當於mysql的表）
                '_all' => [
                    'enabled' => 'false'
                ],
                '_routing' => [
                    'required' => 'true'
                ],
                'properties' => [ //文檔類型設置（相當於mysql的數據類型）
                    'name' => [
                        'type' => 'string',
                        'store' => 'true'
                    ],
                    'age' => [
                        'type' => 'integer'
                    ]
                ]
            ]
        ]
    ]
];

 

實例demo

測試數據

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

使用的是

chinese-poetry\json\poet.song.0.json

寫入數據庫

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

寫入的是時候會出現繁體問題

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

//簡體轉繁體：
$str = "好難";
HanziConvert::convert($str,true);
 
//繁體轉簡體
$str = "好難";
HanziConvert::convert($str);

雖然支持的不是很全，但是寫入個100-200條足夠測試了，或者可以吧你項目新聞類，或者產品類的數據庫作為測試數據

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

        print_r($resech);
