laravel Es搜尋 檢索高亮顯示

**安裝教程，網上都可以查詢到。這裡只簡單文字介紹，詳細步驟可私信我**
1.下載安裝JDK
下載地址https://www.oracle.com/technetwork/java/javase/downloads/index.html
2.配置 JAVA_HOME環境變數
3.開啟命令列視窗，輸入java -version檢視JDK版本 出現版本號 安裝成功
4.下載安裝elasticsearch
下載地址https://www.elastic.co/downloads
5.配置Path環境變數
*6.開啟命令列視窗 執行命令 elasticsearch -d 啟動elasticsearch*
7.瀏覽器開啟 http://localhost:9200 出現詳細資訊 安裝成功
8.安裝Elasticsearch-Head
elasticsearch-head是一個用於瀏覽ElasticSearch叢集並與其進行互動的Web專案
GitHub託管地址：https://github.com/mobz/elasticsearch-head下載並解壓：
9.使用cnpm安裝，這樣速度會快一些 cnpm的安裝方法：
npm install -g cnpm --registry=https://registry.npm.taobao.org
*10.npm run start  啟動成功後，可通過http://localhost:9100進行訪問*
11.由於跨域（Elasticsearch位於9200埠），需要新增配置： E:\elasticsearch-7.1.0\config\elasticsearch.yml中

#新新增的配置行
http.cors.enabled: true
http.cors.allow-origin: "*"

1.首先我們要先連線Es

<?php

namespace App\Http\Controllers;

use App\Models\Article;
use Elasticsearch\ClientBuilder;

class Text extends Controller
{
    //受保護的：只能自己和自己的子類呼叫
    protected $es;

    //建構函式的作用：例項化類的時候自動呼叫，執行每個方法前都會自動執行一次
    public function __construct()
    {
        //連線es
        $this->es = ClientBuilder::create()->setHosts(['localhost:9200'])->build();
    }

    //建立索引（類似於建立資料庫）
    public function createIndex(){
        //設定引數
        //index表示索引名稱，類似於資料庫名稱
        $params = [
            'index'=>'zg4',
            'body'=>[
                'mappings'=>[
                    'properties'=>[//彙總欄位的
                        'title'=>[
                            'type'=>'text',
                            "analyzer" => "ik_max_word",
                            "search_analyzer" => "ik_max_word"
                        ]
                    ]
                ]
            ]
        ];
        $this->es->indices()->create($params);
    }


    //新增文件（給資料庫的某張資料表新增資料）
    public function addDoc(){
        $params = [
            'index'=>'zg3',//類似於資料庫名稱
            'type'=>'article',//類似於資料表名稱(不需要建立的，直接指定就可以了)
            'id'=>1,//當前要新增的資料的主鍵id（自己指定的）
            'body'=>['id'=>1,'name'=>'zhangsan','sex'=>1]//資料
        ];
        $res = $this->es->index($params);
        dump($res);
    }

    //修改文件(給資料庫的某張表修改資料)
    public function updateDoc(){
        $params = [
            'index'=>'zg3',
            'type'=>'article',
            'id'=>1,
            'body'=>[
                //修改的內容
                'doc'=>['name'=>'張三']
            ]
        ];

        $res = $this->es->update($params);
        dump($res);
    }

    //刪除文件（根據id刪除某個資料庫下的某張表下的內容）
    public function deleteDoc(){
        try {
            $params = [
                'index'=>'zg3',
                'type'=>'article',

            ];
            $this->es->delete($params);
            return json(['code'=>0,'msg'=>'刪除成功']);
        }catch (\Exception $e){
            return json(['code'=>1,'msg'=>'刪除失敗']);
        }
    }

    //批量新增文件
    public function addDocAll(){
        $data = Article::select();
        $data = collection($data)->toArray();
        foreach ($data as $k=>$v){

            ];
            $res = $this->es->index($params);
        }
    }

    //es搜尋
    public function esSearch(Request $request)

            return response()->json(['code' => 1, 'msg' => 'word引數不能為空', 'data' => $data]);
        }
        $page = $request->get('page', 1);//接收當前頁，預設值是1
        $size = config('pagesize');//每頁顯示條數
        $from = ($page - 1) * $size;//偏移量
        $params = [

——-更新——
框架安裝:composer require elasticsearch/elasticsearch
elasticsearch -d 啟動elasticsearch/bin/elasticsearch.bat 9200
命令列 切換到head 執行npm run start
