前言

提示：thinkphp中使用Elasticsearch 7.0进行多表的搜索：

thinkphp数据库配置文件

 // Elasticsearch数据库配置信息'elasticsearch' => ['scheme' =>'http','host' => '127.0.0.1','port' => '9200','user' => '','pass' => '','timeout' => 2,],

提示：以下是本篇文章正文内容，下面案例可供参考

一、thinkphp中使用Elasticsearch 7.0进行多表的搜索

示例：thinkphp中使用Elasticsearch 7.0进行多表的搜索

二、使用步骤

1.引入库

直接上代码如下（示例）：

composer require "elasticsearch/elasticsearch": "7.0.*"

2.读入数据

代码如下（示例）：

namespace app\common\model;
use think\facade\Db;
use think\Model;
use Elasticsearch\ClientBuilder;
class Article extends Model
{protected $client;public function __construct($data = []){parent::__construct($data);try {	$this->client = ClientBuilder::create()->setHosts([config('database.connections.elasticsearch.host') . ':' . config('database.connections.elasticsearch.port')])->build();} catch (\Exception $e) {// 输出连接错误信息echo $e->getMessage();exit;}}// 添加文档到Elasticsearchpublic function addDocument(){$articles = Db::name('article')->select();foreach ($articles as $article) {$data = ['id' => $article['id'], // 文章表的 ID'title' => $article['title'],'content' => $article['content'],'category_id' => $article['category_id'], // 文章表的 ID];$params = ['index' => 'articles', // 索引名称'id' => $data['id'], // 文章 ID 作为文档的唯一标识'body' => $data,];$response = $this->client->index($params);}return $response;}// 搜索文档public function searchDocuments($index,$query){$params = ['index' => $index,'body' => ['query' => ['multi_match' => ['query' => $query,'fields' => ['title', 'content'],],],],];$response = $this->client->search($params);return $response;}
}

使用的表

CREATE TABLE `article` (`id` int(11) NOT NULL AUTO_INCREMENT,`category_id` int(11) DEFAULT NULL,`title` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,`content` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=107 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;CREATE TABLE `book` (`id` int(11) NOT NULL AUTO_INCREMENT,`user_id` int(11) DEFAULT NULL,`book` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=21 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;CREATE TABLE `elasticsearch_model` (`id` int(11) NOT NULL AUTO_INCREMENT COMMENT '主键',`model_name` varchar(255) NOT NULL DEFAULT '' COMMENT '模型名称',`index_name` varchar(255) NOT NULL DEFAULT '' COMMENT '索引名称',`created_time` int(11) NOT NULL DEFAULT '0' COMMENT '创建时间',`updated_time` int(11) NOT NULL DEFAULT '0' COMMENT '更新时间',PRIMARY KEY (`id`),UNIQUE KEY `index_name_unique` (`index_name`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8mb4 COMMENT='Elasticsearch 模型配置表';

结果

windwos 上记住 安装 Elasticsearch 7.0 库, 和 kibana-7.0.0-windows-x86_64 图像管理工具

总结

提示：这是简单例子, 注意’fields’ => [‘title’, ‘content’], 尝试使用搜索number型字段,索引报错, 貌似只支持txt类型字段搜索
