🏗 Scene

  • Mid background system
  • Complex front-end query conditions
<?php

namespace App\Http\Controllers;

use App\Models\Post;
use Illuminate\Http\Request;

class PostsController extends Controller
{
    public function index(Request $request)
    {
        return Post::search($request->all())->get();
    }
}

✨ Features

📦 Install

install via composer

composer require illusionist/searcher

🔨 Usage

Add the Searchable trait to your model's

Laravel/Lumen

<?php

namnespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illusionist\Searcher\Contracts\Searchable as SearchableContract;
use Illusionist\Searcher\Eloquent\Searchable;

class Post extends Model implements SearchableContract
{
    use Searchable;
}

ThinkPHP

Your ThinkPHP version must be >= 5.x

<?php

namnespace app\model;

use think\Model;
use Illusionist\Searcher\Contracts\Searchable as SearchableContract;
use Illusionist\Searcher\Eloquent\Searchable;

class Post extends Model implements SearchableContract
{
    use Searchable;
}

Now you can create a database query using the search syntax

Post::search('title:"Hello world" sort:-created_at,published')->get();

💡 Syntax

Note that the spaces between operators don't matter for the string syntax

Exact matches

String syntax

'rating: 0'
'rating = 0'
'title: Hello'               // Strings without spaces do not need quotes
'title: "Hello World"'       // Strings with spaces require quotes
"title: 'Hello World'"       // Single quotes can be used too
'rating = 99.99'
'created_at: "2018-07-06 00:00:00"'

Array syntax

['rating' => 0]
['title' => 'Hello World']
['rating' => 99.99]
['created_at' => '2018-07-06 00:00:00']

Comparisons

String syntax

'title < B'
'rating > 3'
'created_at >= "2018-07-06 00:00:00"'

Array syntax

['title' => ['<', 'B']]
['rating' => ['>', 3]]
['created_at' => ['>=', '2018-07-06 00:00:00']]

Booleans

String syntax

'published'         // published = true
'not published'     // published = false

Array syntax

['published']              // published = true
['not' => 'published']    // published = false

Dates

String syntax

'created_at'                            // created_at is not null
'not created_at'                        // created_at is null

// Year precision
'created_at >= 2020'                    // 2020-01-01 00:00:00 <= created_at
'created_at > 2020'                     // 2020-12-31 23:59:59 < created_at

'not created_at = 2020'                 // created_at < 2020-01-01 00:00:00 and created_at > 2020-12-31 23:59:59

Searchable

If a query term is not boolean or date column, it call getQueryPhraseColumns to get searchable columns.

If no operator is specified in the return value, like is used by default.

For example:

<?php

namnespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illusionist\Searcher\Contracts\Searchable as SearchableContract;
use Illusionist\Searcher\Eloquent\Searchable;

class Post extends Model implements SearchableContract
{
    use Searchable;

    /**
     * Get the columns of the query phrase.
     *
     * @param  string  $phrase
     * @return array
     */
    public function getQueryPhraseColumns($phrase)
    {
        if (is_numeric($phrase)) {
            return ['stars' => '>=', 'comments.stars' => '>='];
        }

        return ['title'];
    }
}

'lonely' // Equivalent to:
$query->where('title', '%lonely%');

'3000' // Equivalent to:
$query->where(function ($query) {
    $query->where('stars', '>=', '3000', 'or')
        ->whereHas('comments', function ($query) {
            $query->where('stars', '>=', '3000')
        });
});

Relationship

If you define a relation method, it will be used to query relationships.

<?php

namnespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illusionist\Searcher\Contracts\Searchable as SearchableContract;
use Illusionist\Searcher\Eloquent\Searchable;

class Post extends Model implements SearchableContract
{
    use Searchable;

    public function comments()
    {
        return $this->hasMany(Comment::class);
    }
}

// Querying Relationship Existence
'comments'                          // $query->has('comments');

// Counting Related Models
'select:comments_count'            // $query->withCount('comments');

// Eager Loading
'select:comments'                  // $query->select('id')->with('comments');
'select:comments.title'            // $query->select('id')->with('comments:id,title')

Configuring searchable columns

Query terms that are not in the searchable property will be discarded, the default value is the real columns of the model table and the relation method name.

<?php

namnespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illusionist\Searcher\Contracts\Searchable as SearchableContract;
use Illusionist\Searcher\Eloquent\Searchable;

class Post extends Model implements SearchableContract
{
    use Searchable;

    protected $searchable = ['author', 'created_at'];
}

'author:kayson title:hello'  // Equivalent to:
$query->where('author', '=', 'kayson');

Configuring boolean and date column

Laravel/Lumen

Use the casts attribute to specify boolean and date columns.

<?php

namnespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illusionist\Searcher\Contracts\Searchable as SearchableContract;
use Illusionist\Searcher\Eloquent\Searchable;

class Post extends Model implements SearchableContract
{
    use Searchable;

    protected $casts = [
        'published' => 'boolean',
        'created_at' => 'datetime',
    ];
}

ThinkPHP

Use the type attribute to specify boolean and date columns.

<?php

namnespace app\model;

use think\Model;
use Illusionist\Searcher\Contracts\Searchable as SearchableContract;
use Illusionist\Searcher\Eloquent\Searchable;

class Post extends Model implements SearchableContract
{
    use Searchable;

    protected $type = [
        'published' => 'boolean',
        'created_at' => 'datetime',
    ];
}

Configuring special keywords

Implement custom keywords and symbiotic columns by overriding the getRelaSearchName function.

selec, order_by, offset is a reserved keywords, please do not conflict with the query terms.

<?php

namnespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illusionist\Searcher\Contracts\Searchable as SearchableContract;
use Illusionist\Searcher\Eloquent\Searchable;

class Post extends Model implements SearchableContract
{
    use Searchable;

    /**
     * Get the real name of the given search column.
     *
     * @param  string  $key
     * @return string|array
     */
    public function getRelaSearchName($key)
    {
       switch ($key) {
            case 'field':
                return 'select';
            case 'sort':
                return 'order_by';
            case 'from':
                return 'offset';
            case 'stars':
                return ['stars', 'comments.stars'];
            default:
                return $key;
        }
    }
}

'field:id,name' // Equivalent to:
$query->select(['id', 'name']);

'stars:3000' // Equivalent to:
$query->where(function ($query) {
    $query->where('stars', '>=', '3000', 'or')
        ->whereHas('comments', function ($query) {
            $query->where('stars', '>=', '3000')
        });
});
