php中文搜索工具,Laravel 下 TNTSearch+jieba-PHP 实现中文全文搜索

TNTSearch+jieba-php这套组合可以在不依赖第三方的情况下实现中文全文搜索;

特别的适合博客这种小项目;

开启php扩展

pdo_sqlite

sqlite3

mbstring

开始:

看到 https://learnku.com 社区新上线的文件推荐功能,作者介绍说是使用了es(elasticsearch)全文搜索功能,于是我开始使用 es (之前没用过),首先想到的是找度娘,结果搜索了好多相关的文档资料,都说需要安装java环境才能使用es,我就想作为php开发如何一定要用java呢?继续搜索寻找其他资料,果然在github里面找到了别人造的轮子laravel-scout-tntsearch;

进入正题:

1、直接

composer require vanry/laravel-scout-tntsearch

2、添加 Provider ;

'providers' => [

...

/**

* TNTSearch 全文搜索

*/

Laravel\Scout\ScoutServiceProvider::class,

Vanry\Scout\TNTSearchScoutServiceProvider::class,

],

3、中文分词

composer require fukuball/jieba-php

4、发布配置项

php artisan vendor:publish --provider="Laravel\Scout\ScoutServiceProvider"

5、配置项config/scout.php中增加 tntsearch

'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',

],

],

6、.env 增加配置项

SCOUT_DRIVER=tntsearch

TNTSEARCH_TOKENIZER=jieba

到这里一切准备就绪,下面我们来测试功能是否有效

控制器中:

public function search(){

$data = Article::search('tnt')->get()->toArray();

dd($data);

}

在模型中我们添加需要搜索的字段:

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

use Laravel\Scout\Searchable;

class Article extends Model

{

use Searchable;

/**

* 索引的字段

*

* @return array

*/

public function toSearchableArray()

{

return $this->only('id', 'title', 'content');

// return $this->toArray();

}

}

生成索引:

php artisan scout:import "App\Model\Article"

大功告成!

注:上面生成索引执行过一次就不需要操作了,当我们新增文章的时候回自动添加索引

执行php artisan scout:import "App\Model\Article" 生成的文件在配置项中 'storage' => storage_path('indexes') 配置
