    Typesense

Typesense is an open source, typo tolerant search engine that is optimized for instant sub-50ms searches,
while providing an intuitive developer experience.
When using the Typesense driver you will need to install the Typesense PHP SDK via the Composer package manager:
composer require typesense/typesense-php

Then, set the SCOUT_DRIVER environment variable as well as your Typesense host and API key credentials within your application's .env file:
SCOUT_DRIVER=typesense
TYPESENSE_API_KEY=xyz
TYPESENSE_HOST=localhost

You can also modify port, path and protocol accordingly:
TYPESENSE_PORT=8108
TYPESENSE_PATH=ts
TYPESENSE_PROTOCOL=https

For more information regarding Typesense, please consult the Typesense documentation.
toSearchableArray

To make your search compatible with Typsense, cast your model id to string and created_at to int32 timestamp as shown below.
<?php

namespace App;

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

class Todo extends Model
{
    use Searchable;
    
     /**
     * Get the indexable data array for the model.
     *
     * @return array
     */
    public function toSearchableArray()
    {
        return array_merge(
            $this->toArray(), 
            [
                // Cast id to string and turn created_at into an int32 timestamp
                // in order to maintain compatibility with the Typesense index definition below
                'id' => (string) $this->id,
                'created_at' => $this->created_at->timestamp,
            ]
        );
    }
}

Collection Schemas and Search Parameters

To setup Typesense collection schemas, in config/scout.php find typesense driver configs and modify model-settings array as shown in example below.
To modify the model query_by attributes you have to setup seach-parameters in model-settings.
Note: query_by is required parameter.
use App\Models\User;

Search Parameters On The Fly

To modify search parameters on the fly you can use setSearchParameters method of Typesense Engine.
use App\Models\Todo;

Todo::search('Do grocceries')->setSearchParameters(['query_by' => 'title, description'])->get();

Available search parameters:
'highlight_start_tag' => '<mark>',
'highlight_end_tag' => '</mark>',
'snippet_threshold' => 30,
'exhaustive_search' => false,
'use_cache' => false,
'cache_ttl' => 60,
'prioritize_exact_match' => true,
'enable_overrides' => true,
'highlight_affix_num_tokens' => 4,

Full list of search parameters and descriptions can be found here.
