前面分享了Xunserch 和 ElasticSearch的安裝，本來是要用Xunserch 的因爲官網項目部需要太強大的插件，但是安裝不給力，各種錯誤，最後用ElasticSearch。。。其實ElasticSearch並不太難，，， 不說了 直接上代碼
先說下我的設計模式：
後臺添加數據的同時王es裏面插入索引， es6.0版本後一個索引只能插入一個type，所以es每個索引對應數據表， es存放前端要顯示的字段即可，沒必要全部字段都存在裏面。 插入或者更新是調用一個公共方法。。。 搜索調用搜索接口
優化點 如果你的集羣只有一個節點，這不要設置副本數，不然健康值會變成yellow，設置爲0即可
阿里雲的dts可以自動把mysql數據庫的數據添加和更新索引到ES 但是需要付費。。。這個不做過多的說明
1.在 項目配置文件 web.php (高級模板main.php) 中的components中添加配置：
//現使用 es
'elasticsearch' => [
'class' => 'yii\elasticsearch\Connection',
//默認爲true 如果單節點 設爲false 不然會連接錯誤
'autodetectCluster' => false,
'nodes' => [
['http_address' => '127.0.0.1:9200'],
],
],
2.搜索接口
/**
* auth - rk
* 獲取全站搜索數據
* 支持分詞搜索和 多條件+多字段搜索
*/
public function actionSearch(){
if(Yii::$app->request->isPost){
$searchData = Yii::$app->request->post('name','');

$offset = ($page-1)*$pageSize;
$searchData =trim($searchData);

//高亮數據
$highlight = [

$sort = ['sort' => ['order' => 'desc']];
//->query($query)->orderBy($sort)->asArray()->all() 'terms'=> $where

$resArr[$val]['data'] = $res??[];
}
//搜索數據存儲到後臺
$searchModel = new Search();
//先判斷是否存在搜索數據 存在更新次數

}
}else{

$searchModel->content = $searchData;
$searchModel->save();
}
//xunsearch
// $db = \Yii::$app->xunsearch->getDatabase('mmc_uav',true);
// $xs = $db->xs;
// $search = $db->getSearch();
// $index = $db->getIndex();
// var_dump($search);die;
$data['res_code']='200';
$data['res_msg']='success';
$data['host'] = Yii::$app->request->hostInfo;

- 手動添加索引和更新
if( $model->save()){

ElasticSearch::es('product',$model->attributes);
return $this->redirect(['view', 'id' => $model->id]);
}
//最終效果
