以下由Laravel教學專欄為大家介紹如何輕鬆整合新版Elasticsearch7.9中文搜尋到Laravel7項目，希望對需要的朋友有幫助！
只需五個步驟：
1、啟動整合ik中文分詞外掛程式的Elasticsearch7.9 Docker映像
課程推薦→：《elasticsearch全文搜尋實戰》（實戰影片）
2、Laravel7 配置Scout
3、配置Model模型
4、導入資料
5、搜尋
搜尋範圍
#結果權重
搜尋頁面
主要是部落格剛好想做個搜尋,順便就整理成文章
Laravel Elasticsearch 很多前輩都寫過教程和案例,但是隨著Elasticsearch和laravel的版本升級以前的文章很多都不適用新版本的,建議大家使用任何開源專案時應該過一遍文件以目前使用的版本文件為主,教程為輔
ik中文分詞外掛程式的Elasticsearch$ docker pull ar414/elasticsearch-7.9-ik-plugin
本地映射到docker容器內，防止docker重新啟動資料遺失
$ mkdir -p /data/elasticsearch/data $ mkdir -p /data/elasticsearch/log $ chmod -R 777 /data/elasticsearch/data $ chmod -R 777 /data/elasticsearch/log
docker run -d -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -v /data/elasticsearch/data:/var/lib/elasticsearch -v /data/elasticsearch/log:/var/log/elasticsearch ar414/elasticsearch-7.9-ik-plugin

$ composer require laravel/scout $ composer require 輕鬆整合新版Elasticsearch7.9中文搜尋到Laravel7項目
$ php artisan vendor:publish --provider="Laravel\Scout\ScoutServiceProvider"Copied File [\vendor\laravel\scout\config\scout.php] To [\config\scout.php]Publishing complete.
##第一種：在.env
SCOUT_DRIVER=Matchish\ScoutElasticSearch\Engines\ElasticSearchEngine
config/scout.php
直接修改預設驅動'driver' => env('SCOUT_DRIVER', 'algolia')改为'driver' => env('SCOUT_DRIVER', 'Matchish\ScoutElasticSearch\Engines\ElasticSearchEngine')ELASTICSEARCH_HOST=172.17.0.1:9200
'providers' => [ // Other Service Providers \Matchish\ScoutElasticSearch\ElasticSearchServiceProvider::class],
$ php artisan config:clear
通过博客右上角的搜索框可以搜索到与关键词相关的文章，从以下几点匹配
涉及到2张 Mysql表 以及字段
创建索引配置文件（config/elasticsearch.php）
$ touch config/elasticsearch.php
elasticsearch.php 配置字段映射
<?phpreturn [ 'indices' => [ 'mappings' => [ 'blog-articles' => [ "properties"=> [ "content"=> [ "type"=> "text", "analyzer"=> "ik_max_word", "search_analyzer"=> "ik_smart" ], "tags"=> [ "type"=> "text", "analyzer"=> "ik_max_word", "search_analyzer"=> "ik_smart" ], "title"=> [ "type"=> "text", "analyzer"=> "ik_max_word", "search_analyzer"=> "ik_smart" ] ] ] ] ],];
laravel天下无敌 -> laravel，天下无敌,天下,无敌
laravel天下无敌 -> laravel，天下无敌
建议先看一遍 Laravel Scout 使用文档
引入Laravel Scout
namespace App\Models\Blog;
use Laravel\Scout\Searchable;
class Article extends BlogBaseModel
{
use Searchable;
}指定索引(刚刚配置文件中的elasticsearch.indices.mappings.blog-articles)
/**
* 指定索引
* @return string
*/
public function searchableAs()
{
return 'blog-articles';
}设置导入索引的数据字段
/**
* 设置导入索引的数据字段
* @return array
*/
public function toSearchableArray()
{
return [
'content' => ArticleContent::query()
->where('article_id',$this->id)
->value('content'),
'tags' => implode(',',$this->tags),
'title' => $this->title
];
}指定 搜索索引中存储的唯一ID
/**
* 指定 搜索索引中存储的唯一ID
* @return mixed
*/
public function getScoutKey()
{
return $this->id;
}
/**
* 指定 搜索索引中存储的唯一ID的键名
* @return string
*/
public function getScoutKeyName()
{
return 'id';
}其实是将数据表中的数据通过Elasticsearch导入到Lucene
Elasticsearch 是 Lucene 的封装，提供了 REST API 的操作接口
php artisan scout:import
php artisan scout:import ${model}
$ php artisan scout:import "App\Models\Blog\Article"Importing [App\Models\Blog\Article]Switching to the new index 5/5 [⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬⚬] 100%[OK] All [App\Models\Blog\Article] records have been imported.
导入失败,常见原因:
$ curl -XGET http://localhost:9200/blog-articles/_mapping?pretty{
"blog-articles_1598362919" : {
"mappings" : {
"properties" : {
"__class_name" : {
"type" : "text", "fields" : {
"keyword" : {
"type" : "keyword", "ignore_above" : 256 }
}
}, "content" : {
"type" : "text", "analyzer" : "ik_max_word", "search_analyzer" : "ik_smart"
}, "tags" : {
"type" : "text", "analyzer" : "ik_max_word", "search_analyzer" : "ik_smart"
}, "title" : {
"type" : "text", "analyzer" : "ik_max_word", "search_analyzer" : "ik_smart"
}
}
}
}}创建一个测试命令行
$ php artisan make:command ElasticTest
代码
<?phpnamespace App\Console\Commands;use App\Models\Blog\Article;use App\Models\Blog\ArticleContent;use Illuminate\Console\Command;use Illuminate\Support\Carbon;class ElasticTest extends Command{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'elasticsearch {query}';
/**
* The console command description.
*
* @var string
*/
protected $description = 'elasticsearch test';
/**
* Create a new command instance.
*
* @return void
*/
public function __construct()
{
parent::__construct();
}
/**
* Execute the console command.
*
* @return mixed
*/
public function handle()
{
//
$startTime = Carbon::now()->getPreciseTimestamp(3);
$articles = Article::search($this->argument('query'))->get()->toArray();
$userTime = Carbon::now()->getPreciseTimestamp(3) - $startTime;
echo "耗时(毫秒)：{$userTime} \n";
//content在另外一张表中，方便观察测试 这里输出
if(!empty($articles)) {
foreach($articles as &$article) {
$article = ArticleContent::query()->where('article_id',$article['id'])->value('content');
}
}
var_dump($articles);
}}$ php artisan elasticsearch 周杰伦
//ONGR\ElasticsearchDSL\Highlight\Highlight ArticleModel::search($query,function($client,$body) {
$higlight = new Highlight();
$higlight->addField('content',['type' => 'plain']);
$higlight->addField('title');
$higlight->addField('tags');
$body->addHighlight($higlight);
$body->setSource(['title','tags']);
return $client->search(['index' => (new ArticleModel())->searchableAs(), 'body' => $body->toArray()]);
})->raw();复杂自定义查询回调中的$client和$body，可根据这两个包进行灵活操作
$client 官方 elasticsearch/elasticsearch package（https://packagist.org/packages/elasticsearch/elasticsearch）
$body ongr/elasticsearch-dsl package（https://packagist.org/packages/ongr/elasticsearch-dsl）
