Boost your Search Functionality with Laravel Scout

Discover how to integrate full-text search into your Laravel application using Laravel Scout. Learn installation, setup, and examples.

The user experience of current web apps is greatly enhanced by the presence of search capability. Including a powerful search function might be crucial when developing an e-commerce platform, blog, or any other content-driven website. Laravel Scout provides an easy-to-use way to integrate full-text search into your Laravel applications, facilitating the implementation of robust and adaptable search features.

This post will explain what Laravel Scout is, explain how to install and set it up, and provide code examples to show you how to use it.

What is Laravel Scout?

A full-text search module for Laravel applications, Laravel Scout is driver-based. Because of its integrations with several search engines, you may quickly and easily deploy full-text search capability.

Scout is especially well-known for its smooth integration with Algolia, a quick and dependable search-as-a-service platform, even though it supports a number of search engines. Also Click for integrate authentication in your laravel website without any code

Important Laravel Scout Features

• Easy Integration: Easily provide your models full-text search features.
• Real-Time Indexing: When a model is added, modified, or removed, search indexes are automatically updated.
• Search Customisation: Tailor search terms and returns to your own requirements.
• Support for Multiple Drivers: Works with a number of search engines, such as Elasticsearch, MeiliSearch, and Algolia.

Installing Laravel Scout

Before you start using Laravel Scout, you’ll need to install it in your Laravel application. Here’s how you can set it up:

Step 1: Install Laravel Scout

First, you need to install Laravel Scout via Composer. Run the following command in your terminal:

composer require laravel/scout

Step 2: Publish the Scout Configuration

Next, publish the Scout configuration file using the artisan command:

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

This will create a config/scout.php file where you can configure Scout’s settings, including your search driver and indexing options.

Step 3: Configure Your Search Driver

Laravel Scout requires a search driver to perform searches. By default, Scout is configured to use Algolia, but you can choose other drivers like MeiliSearch or Elasticsearch.

To configure Algolia, you’ll need to add your Algolia API credentials in your .env file:

env:

ALGOLIA_APP_ID=your-algolia-app-id
ALGOLIA_SECRET=your-algolia-api-key

Make sure your config/scout.php file reflects these changes:

'driver' => env('SCOUT_DRIVER', 'algolia'),

'algolia' => [
    'id' => env('ALGOLIA_APP_ID', ''),
    'secret' => env('ALGOLIA_SECRET', ''),
],

Step 4: Add the Searchable Trait to Your Models

For Scout to know which models should be searchable, you need to add the Searchable trait to those models. Here’s how to add it to a model, for example, a Post model:

namespace App\Models;

use Laravel\Scout\Searchable;
use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    use Searchable;

    // Your model's properties and methods
}

With the Searchable trait, Scout automatically updates the search index whenever a model is created, updated, or deleted.

Using Laravel Scout in Your Application

Once you’ve set up Laravel Scout, you can start using it to perform searches. Below are some examples of how to use Scout to perform searches and customize the search functionality.

Performing a Basic Search

Performing a search with Laravel Scout is straightforward. Here’s how you can search for posts containing a specific term:

use App\Models\Post;

$searchResults = Post::search('laravel')->get();

This query will search the posts table for any records that contain the term “laravel” in the searchable fields.

Customizing Search Queries

Laravel Scout allows you to customize search queries to better match your application’s needs. For instance, you might want to only search published posts:

$searchResults = Post::search('laravel')->where('published', true)->get();

This query adds a condition to the search, ensuring that only published posts are returned in the results.

Paginating Search Results

$searchResults = Post::search('laravel')->paginate(10);

This will return 10 results per page, with pagination links available in your views.

Customizing Indexing Behavior

Sometimes, you may want to control which attributes of your model are indexed. You can do this by overriding the toSearchableArray method in your model:

class Post extends Model
{
    use Searchable;

    public function toSearchableArray()
    {
        $array = $this->toArray();

        // Customize array...
        return [
            'title' => $array['title'],
            'content' => $array['content'],
        ];
    }
}

This method allows you to specify exactly which fields should be indexed, providing greater control over your search data.

Queueing Indexing Operations

For large datasets, it’s recommended to queue the indexing operations to avoid performance issues. To enable this, set the queue configuration option to true in the config/scout.php file:

'queue' => true,

You should also ensure that your Laravel application is configured to handle queued jobs properly.

Top Tips for Using Laravel Scout

Take into account the following recommended practices to get the most out of Laravel Scout:

• Optimise Data That Is Searchable: Index only the fields that are relevant to a search. Over-indexing can raise storage costs and negatively impact search results.
• Effectively Use Filters: Filters can be used, particularly in huge datasets, to improve relevance and narrow down search results.
• Update Indexes Often: Make use of Scout’s automatic indexing features to make sure your search indexes are always current with the most recent information.
• Track Search Performance: Keep an eye on your search performance and adjust your queries as necessary if you’re using Algolia or another third-party service.

With this, You don’t need to worry about writing additional code to provide search capabilities to your website when you use this approach of the Laravel package. This program creates functionality while saving you time.
