elasticsearch简单的增删改查与高亮显示

原生方式 添加索引

$hosts = [
    '127.0.0.1:9200'
];
$client = \Elasticsearch\ClientBuilder::create()->setHosts($hosts)->build();

// 创建索引
$params = [
    'index' => 'goods',
    'body' => [
        'settings' => [
            'number_of_shards' => 5,
            'number_of_replicas' => 1
        ],
        'mappings' => [
            '_doc' => [
                '_source' => [
                    'enabled' => true
                ],
                'properties' => [
                    'title' => [
                        'type' => 'keyword'
                    ],
                    'desn' => [
                        'type' => 'text',
                        'analyzer' => 'ik_max_word',
                        'search_analyzer' => 'ik_max_word'
                    ]
                ]
            ]
        ]
    ]
];
$response = $client->indices()->create($params);

更新数据

$hosts = [
    '127.0.0.1:9200',
];
$client = \Elasticsearch\ClientBuilder::create()->setHosts($hosts)->build();
// 写文档
$params = [
    'index' => 'goods',
    'type' => '_doc',
    'id' => $model->id,
    'body' => [
        'title' => $model->title,
        'desn' => $model->desn,
    ],
];
$response = $client->index($params);

搜索数据

$hosts = [
    '127.0.0.1:9200',
];
$client = \Elasticsearch\ClientBuilder::create()->setHosts($hosts)->build();
$params = [
    'index' => 'goods',
    'type' => '_doc',
    'body' => [
        'query' => [
            'match' => [
                'title'=>[
                    'query' => '手机'
                ]
            ]
        ]
    ]
];
$results = $client->search($params);
dump($results);

 

 

 

封装方法使用

        }
        //可以将数据发送到视图
