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 IDtitle $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;}
}?php

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 例如以上就是今天要讲的内容本文仅仅简单介绍了Elasticsearch的使用
