Laravel 5.1 XunSearch

Laravel 5.1 package for full-text search over Eloquent models based on XunSearch.

Installation

Require this package in your composer.json and run composer update:

{
	"require": {
        "davin-bao/laravel-xun-search": "dev-master"
	}
}

After updating composer, add the ServiceProvider to the providers array in app/config/app.php

'providers' => [
	DavinBao\LaravelXunSearch\ServiceProvider::class,
],

If you want to use the facade to search, add this to your facades in app/config/app.php:

'aliases' => [
	'Search' => DavinBao\LaravelXunSearch\Facade::class,
],

Configuration

Publish the config file into your project by running:

php artisan vendor:publish --provider="DavinBao\LaravelXunSearch\ServiceProvider"

###Basic In published config file add descriptions for models which need to be indexed, for example:

//@see http://www.xunsearch.com/doc/php/guide/ini.guide
"project" => [
    "project.name" => "demo",
    "project.default_charset" => "utf-8",
    "server.index" => "127.0.0.1:8383",
    "server.search" => "127.0.0.1:8384",
    //remember change FIELD_LABEL_DEFAULT_SEARCH_PK value in Config.php
    "primary_key" => [
        "type" => "id"
    ],
    //remember change FIELD_LABEL_DEFAULT_CLASS_ID value in Config.php
    "class_uid" => [
        "index" => "both"
    ],
    //remember change FIELD_LABEL_DEFAULT_DB_PK value in Config.php
    "id" => [
        "type" => "numeric"
    ],
    "username" => [
        "type" => "title"
    ],
    "email" => [
        "index" => "both"
    ],
    "last_seen" => [
        "type" => "numeric"
    ],
    "role" => [
        "index" => "both"
    ],
    "uri" => [
        "index" => "both"
    ],
    "action" => [
        "index" => "both"
    ],
],

'index' => [
	
	// ...

	namespace\FirstModel::class => [
		'fields' => [
			'name', 'full_description', // fields for indexing
		],
		'primary_key' => 'id'  //primary_key name in DB, default 'id'
	],
	
	namespace\SecondModel::class => [
		'fields' => [
			'name', 'short_description', // fields for indexing
		]
	],
	
	// ...
	
],

Usage

Artisan commands

Initialize or rebuild search index

For building of search index run:

php artisan search:rebuild --verbose

Clear search index

For clearing of search index run:

php artisan search:clear

Filtering of models in search results

For filtering of models in search results each model's class can implements SearchableInterface. For example:

use Illuminate\Database\Eloquent\Model;
use DavinBao\LaravelXunSearch\Model\SearchableInterface;

class Dummy extends Model implements SearchableInterface
{
        // ...

        /**
         * Get id list for all searchable models.
         */
        public static function searchableIds()
        {
            return self::wherePublish(true)->lists('id');
        }

        // ...
}

Partial updating of search index

For register of necessary events (save/update/delete) use DavinBao\LaravelXunSearch\Model\SearchTrait in target model:

    use Illuminate\Database\Eloquent\Model;
    use DavinBao\LaravelXunSearch\Model\SearchableInterface;
    use DavinBao\LaravelXunSearch\Model\SearchTrait;

    class Dummy extends Model implements SearchableInterface
    {
        use SearchTrait;
    
        // ...
    }

Query building

Build query in several ways:

Using constructor:

By default, queries which will execute search in the phrase entirely are created.

Simple queries

$query = Model::getSearch()->addQuery("clock"); // search by all fields.
// or 
$query = Model::getSearch()->addQuery('name:clock'); // search by 'name' field.
// or
$query = Model::getSearch()->addQuery('name:clock'); // filter by 'short_description' field.

$Ids = Model::getSearch()->addQuery('name:clock')->getIDList(); // filter by 'short_description' field.

Getting of results

For built query are available following actions:

Get all found models

$models = $query->search();

Get all found models ID

$models = $query->getIDList();

Get count of results

$count = $query->count();

Get limit results with offset

$models = $query->limit(5, 10)->get(); // Limit = 5 and offset = 10

Sort

$query = $query->setSort('chrono', true);

Highlighting of matches

Highlighting of matches is available for any html fragment encoded in utf-8 and is executed only for the last executed request.

$docs = $search->setQuery('测试')->setLimit(5)->search();
foreach ($docs as $doc)
{
   $subject = $search->highlight($doc->subject); // 高亮处理 subject 字段
   $message = $search->highlight($doc->message); // 高亮处理 message 字段
   echo $doc->rank() . '. ' . $subject . " [" . $doc->percent() . "%] - ";
   echo date("Y-m-d", $doc->chrono) . "\n" . $message . "\n";
}
