Laravel Scout Guide: Understand Full-Text Search

Does your Laravel website have thousands of blogs and articles? Or maybe you have a massive arsenal of products in your eCommerce website? Or, have you created a vast, dynamic knowledge base with a bunch of customized categories? Then the old-school, clunky search bars may not cut it on your website.

So the web development services use Laravel Scout for full-text search functionalities. This robust package seamlessly integrates with your Laravel application. So the need for complex search implementations will be eliminated. That empowers you to deliver a seamless user experience.

But how does it work? And how do you implement it? Also, what kind of benefits does using Laravel Scout offer? But first, let’s see what Laravel Scout is.

What is the Laravel Scout?

Laravel Scout is one of the powerful packages for Laravel that offers a straightforward, driver-based solution for implementing full-text search on your Eloquent models. It leverages popular search engines like Algolia or Elasticsearch to deliver efficient and accurate search functionality.

With Laravel Scout, configuring and indexing model data is effortless. That allows users to perform advanced search operations across multiple attributes. It also supports features such as search term highlighting and pagination.

To fully utilize Scout, the Laravel developers should familiarize themselves with the supported search drivers, index management techniques, and optimization strategies. By embracing Laravel Scout, you can greatly enhance the search capabilities of your Laravel application. That provides users with a seamless and robust search experience.

How does Laravel Scout Work?

Laravel Scout is a package in the Laravel PHP framework designed to provide a simple, driver-based solution for adding full-text search functionality to Eloquent models. It integrates with popular search engines like Algolia and Elasticsearch. So you can easily implement powerful search capabilities in your Laravel applications.

Laravel Scout operates under the hood with a few key components working together:

Drivers: Scout offers different drivers for powering your search, each with its own strengths and weaknesses. Popular choices include:

• Algolia: A hosted search engine known for its blazing speed and scalability, perfect for large datasets.
• Meilisearch: A self-hosted alternative to Algolia, offering similar performance and flexibility at a lower cost.
• Database: Utilizes your existing database with full-text indexes for basic search functionality, suitable for smaller datasets.

Searchable Models: You declare your Eloquent models as “searchable” by adding the Searchable trait. This tells Scout which fields to index and how to interact with the data.

Model Observers: Scout uses model observers to automatically keep your search indexes in sync with your database. When a model is created, updated, or deleted, the observer triggers an update in the corresponding search index.

Search Queries: You can perform searches on your models using the search method provided by Scout. This method allows you to specify keywords, phrases, filters, and sorting options.

Search Results: The driver returns a collection of matching models, seamlessly rehydrated from your database. You can then use these models in your application to display search results to your users.

Here’s a breakdown of the workflow:

1. User submits a search query.
2. Scout parses the query and sends it to the chosen driver.
3. The driver searches its index and returns a list of matching IDs.
4. Scout retrieves the corresponding models from your database.
5. These models are sent back to your application as search results.

This workflow ensures that your search results are always updated, regardless of the driver you choose.

How to Implement Laravel Scout for Full-text Search?

Laravel Scout is your key to unlocking intuitive full-text search functionalities within your Eloquent models. This Laravel package eliminates the need for complex search implementations for a seamless user experience.

Implementing Laravel Scout for full-text search is a straightforward process, involving these key steps:

Step 1: Install Laravel Scout

Use Composer to install the Laravel Scout package:

composer require laravel/scout

Step 2: Configure Scout

Laravel Scout supports multiple search engines, and you need to configure it for the one you want to use. Open the config/scout.php file and set the appropriate driver and configuration options. For example, if you want to use Algolia, configure the Algolia credentials:

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

Step 3: Model Setup

In the Eloquent model that you want to make searchable, use the Searchable trait:

use Laravel\Scout\Searchable;
class YourModel extends Model
{
    use Searchable;
}

Implement the toSearchableArray method in your model to define which attributes should be indexed:

public function toSearchableArray()
{
    return [
        'id' => $this->id,
        'title' => $this->title,
        // Add other searchable attributes
    ];
}

Step 4: Indexing Data

After setting up the model, you need to sync your existing data with the search index. Run the following Artisan command to index your records:

php artisan scout:import "App\Models\YourModel"

Replace “App\Models\YourModel” with the actual namespace of your model.

Step 5: Performing Searches

You can now perform searches using the search method on your model:

$results = YourModel::search('Search Query')->get();

Laravel Scout will use the configured search engine (e.g., Algolia) to execute the search and return relevant results.

Step 6: Pagination

You can use Laravel’s built-in pagination methods to paginate the search results:

$results = YourModel::search('Search Query')->paginate(10);

Adjust the paginate method parameter according to your desired number of results per page.

Step 7: Displaying Results

Display the search results in your view as needed. Iterate through the $results collection to show relevant information.

@foreach($results as $result)
    {{ $result->title }}
    {{-- Display other attributes --}}
@endforeach

I know this process can be a little too technical for those without the skills and know-how. Feel free to refer to the Laravel Scout documentation and experiment to find the perfect configuration for your project. Or you can consult with our dedicated Laravel experts for assistance with Scout.
