Laravel + Scout + Elasticsearch 全文搜索

之前一直直接使用Elasticsearch完成搜索，最近发现了Scout这个Laravel插件，决定试用一下，底层的搜索引擎还是用了Elasticsearch，当然还可以使用Algolia，主要还有数据统计的地方会用到ES，所以底层就都用ES来存储了。

1. 安装Elasticsearch

1.1 docker 安装ES

docker pull docker.elastic.co/elasticsearch/elasticsearch:7.10.0
docker run -d --name elastic -p 9201:9200 -p 9301:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms1g -Xmx1g" docker.io/elasticsearch:7.10.0

1.2 安装IK分词

docker exec -it f80b12611cd6 /bin/bash
cd bin
./elasticsearch-plugin -v install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.10.0/elasticsearch-analysis-ik-7.10.0.zip

1.3 重启docker镜像

docker restart f80b12611cd6

2. Laravel集成Scout

2.1 安装依赖

composer require elasticsearch/elasticsearch

composer require tamayo/laravel-scout-elastic:8.0.3 // 因为我的php版本只有7.1

composer require laravel/scout

php artisan vendor:publish

选择 Laravel\Scout\ScoutServiceProvider

2.2 配置参数

scout.php文件

3. 搜索内容

3.1 更新模型

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Laravel\Scout\Searchable;

class PlatformItemStock extends Base
{
    use Searchable;

    protected $table = "platform_item_stock";

    public $timestamps = true;

    protected $guarded = [];

    public function attributes() {
        return $this->hasMany(PlatformItemAttribute::class, 'itemsStockId', 'id');
    }

    public function skuImage()
    {
        return $this->belongsTo(Attachment::class, 'itemSkuImageId');
    }

    public function item()
    {
        return $this->belongsTo(PlatformItem::class, 'itemId');
    }

    protected function makeAllSearchableUsing($query)
    {
        return $query->with(['item', 'item.category', 'item.brand', 'item.series', 'item.material']);

    }
}

3.2 引入模型内容

php artisan scout:import "App\Models\PlatformItemStock"

image

3.3 搜索调用

public function search($query, $num)
    {
        return $this->model->search($query)->paginate($num);
    }

3.4 更新搜索内容

public function store($query)
    {
        $result = $this->model->create($query);
        $result->with(['item', 'item.category', 'item.brand', 'item.series', 'item.material'])->searchable();
        return $result;
    }

    public function update($id, $query)
    {
        $res = $this->model->find($id);
        $res->update($query);
        $res->with(['item', 'item.category', 'item.brand', 'item.series', 'item.material'])->searchable();
        return $res;
    }

ps.临时修复laravel scout elastic的bug(因为我的docker里面php版本太低了，没办法升级安装包，找时间更新一下版本)

打开vendor/tamayo/laravel-scout-elastic/src/Engines/ElasticsearchEngine.php

$result['hits']['total'] = $result['hits']['total']['value'];
// 上面增加这一行
$result['nbPages'] = $result['hits']['total'] / $perPage;
