Filament Natural Language Filter

A simple Filament filter that converts natural language text into database queries using AI.

Installation

composer require hayderhatem/filament-natural-language-filter

Configuration

1. Publish the config file:

php artisan vendor:publish --tag="filament-natural-language-filter-config"

2. Add your OpenAI API key to your .env file:

OPENAI_API_KEY=your-openai-api-key-here

Usage

Add the filter to your Filament table:

use HayderHatem\FilamentNaturalLanguageFilter\Filters\NaturalLanguageFilter;

public function table(Table $table): Table
{
    return $table
        ->columns([
            // your columns
        ])
        ->filters([
            NaturalLanguageFilter::make()
                ->availableColumns([
                    'id',
                    'name', 
                    'email',
                    'status',
                    'created_at',
                    'updated_at'
                ])
        ]);
}

Search Modes

You can configure how the filter triggers searches:

Submit Mode (Default) - Search on Enter key

NaturalLanguageFilter::make()
    ->availableColumns(['name', 'email', 'status'])
    ->submitSearch() // Users press Enter to search

Live Mode - Search as you type

NaturalLanguageFilter::make()
    ->availableColumns(['name', 'email', 'status'])
    ->liveSearch() // Search happens automatically as user types

Manual Mode Configuration

NaturalLanguageFilter::make()
    ->availableColumns(['name', 'email', 'status'])
    ->searchMode('live') // or 'submit'

When to Use Each Mode

Submit Mode (Default) - Best for:

• Large datasets where live search might be slow
• Complex queries that users want to perfect before searching
• Reducing API calls to OpenAI (only search when user is ready)

Live Mode - Best for:

• Instant feedback and better user experience
• Smaller datasets where performance isn't a concern
• Users who prefer immediate results as they type

How it works

1. User enters natural language: "show users named john created after 2023"
2. AI processes the text: Converts it to structured filters based on your available columns
3. Database query is built: WHERE name LIKE '%john%' AND created_at > '2023-01-01'
4. Results are filtered: Table shows matching records

Examples

• "users named john" → WHERE name LIKE '%john%'
• "active users" → WHERE status = 'active'
• "created after 2023" → WHERE created_at > '2023-01-01'
• "email contains gmail" → WHERE email LIKE '%gmail%'

Universal Language Support 🌍

The filter supports ANY language with automatic AI translation and understanding:

Multi-Language Examples

English:

• "show users named john" → WHERE name LIKE '%john%'
• "created after 2023" → WHERE created_at > '2023-01-01'

Arabic (العربية):

• "الاسم يحتوي على أحمد" → WHERE name LIKE '%أحمد%'
• "أنشئ بعد 2023" → WHERE created_at > '2023-01-01'

Spanish (Español):

• "usuarios con nombre juan" → WHERE name LIKE '%juan%'
• "creado después de 2023" → WHERE created_at > '2023-01-01'

French (Français):

• "nom contient marie" → WHERE name LIKE '%marie%'
• "créé après 2023" → WHERE created_at > '2023-01-01'

German (Deutsch):

• "benutzer mit namen hans" → WHERE name LIKE '%hans%'
• "erstellt nach 2023" → WHERE created_at > '2023-01-01'

Chinese (中文):

• "姓名包含张三" → WHERE name LIKE '%张三%'
• "2023年后创建" → WHERE created_at > '2023-01-01'

Japanese (日本語):

• "田中という名前のユーザー" → WHERE name LIKE '%田中%'
• "2023年以降に作成" → WHERE created_at > '2023-01-01'

How It Works

1. AI Language Detection: Automatically detects the input language
2. Natural Understanding: Maps language-specific keywords to operators
3. Value Preservation: Keeps original values in their native language/script
4. Mixed Language: Handles mixed-language queries seamlessly

Mixed Language Queries

The AI can handle mixed-language queries naturally:

• "name يحتوي على john" ✅
• "usuario con email gmail.com" ✅
• "姓名 contains 张三" ✅
