Laravel 下 TNTSearch+jieba-PHP 实现中文全文搜索

##
TNTSearch+jieba-php 实现中文全文搜索；

##

1.   laravel new tntsearch   (创建项目)

2. php artisan make:model Models/Article -m （建表，模型）

3. 修改 .env 数据库配置项；
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret

4. php artisan make:model Models/Article -m （建表，模型）

5: 再确认 php 开启了以下扩展
pdo_sqlite
sqlite3
mbstring

6. composer 加载 laravel-scout-tntsearch扩展包
composer require vanry/laravel-scout-tntsearch

7.添加 Provider  config/app.php；
'providers' => [

    // ...

    /**
     * TNTSearch 全文搜索
     */
    Laravel\Scout\ScoutServiceProvider::class,
    Vanry\Scout\TNTSearchScoutServiceProvider::class,
],

6. composer 加载 中文分词 require jieba-php

  composer require fukuball/jieba-php

7.发布配置项
php artisan vendor:publish --provider="Laravel\Scout\ScoutServiceProvider"

8.配置项中增加 tntsearch  config/scout.php ；

'tntsearch' => [
    'storage' => storage_path('indexes'), //必须有可写权限
    'fuzziness' => env('TNTSEARCH_FUZZINESS', false),
    'searchBoolean' => env('TNTSEARCH_BOOLEAN', false),
    'asYouType' => false,

    'fuzzy' => [
        'prefix_length' => 2,
        'max_expansions' => 50,
        'distance' => 2,
    ],

    'tokenizer' => [
        'driver' => env('TNTSEARCH_TOKENIZER', 'default'),

        'jieba' => [
            'dict' => 'small',
            //'user_dict' => resource_path('dicts/mydict.txt'), //自定义词典路径
        ],

        'analysis' => [
            'result_type' => 2,
            'unit_word' => true,
            'differ_max' => true,
        ],

        'scws' => [
            'charset' => 'utf-8',
            'dict' => '/usr/local/scws/etc/dict.utf8.xdb',
            'rule' => '/usr/local/scws/etc/rules.utf8.ini',
            'multi' => 1,
            'ignore' => true,
            'duality' => false,
        ],
    ],

    'stopwords' => [
        '的',
        '了',
        '而是',
    ],
],

9.增加配置项  .env ：
SCOUT_DRIVER=tntsearch
TNTSEARCH_TOKENIZER=jieba

10.型中定义全文搜索；
/app/StoreCourse.php

<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Laravel\Scout\Searchable;

class StoreCourse extends Model
{

  use Searchable;
  protected $table = "stores_courses";
  public $timestamps = false;

  protected $primaryKey = 'id';
  protected $guarded = [];
  protected $fields = [];

  /**
 * 索引的字段
  *
 * @return array
 */  public function toSearchableArray()
 {  return $this->only('id', 'name', 'image_url');

  // return $this->toArray();
  }

}

11.  php 默认的 memory_limit 是 128M；
为了防止 PHP Fatal error: Allowed memory size of n bytes exhausted ；增加到 256M 以解决内存不够报错的问题;


public function boot()
{
    /**
     * 增加内存防止中文分词报错
     */
    ini_set('memory_limit', "256M");
}

12. 生成索引
php artisan scout:import "App\StoreCourse"

13. 使用

StoreCourse::search('功能齐全的搜索引擎')->get()->toArray()
