This package makes is the Elasticsearch driver for Laravel Scout.
You can install the package via composer:
composer require thomasjsn/laravel-scout-elasticYou must add the Scout service provider and the package service provider in your app.php config:
// config/app.php
'providers' => [
...
Laravel\Scout\ScoutServiceProvider::class,
...
ScoutEngines\Elasticsearch\ElasticsearchProvider::class,
],Then you should publish the Elasticsearch configuration using the vendor:publish Artisan command.
php artisan vendor:publish --provider="ScoutEngines\Elasticsearch\ElasticsearchProvider"
You must have a Elasticsearch server up and running, indices can be created with an Artisan command; see below.
After you've published the Laravel Scout package configuration:
// config/scout.php
// Set your driver to elasticsearch
'driver' => env('SCOUT_DRIVER', 'elasticsearch'),You may define custom mappings for Elasticsearch fields in the config. See examples in the config file.
If you prefer storing mappings in models, you may create a static public method mapping() in each particular model:
class Article extends Model
{
// ...
public static function mapping() {
return [
'location' => [
'type' => 'geo_point'
],
];
}
// ...
}And then use it in the config file:
'indices' => [
'realestate' => [
'settings' => [
"number_of_shards" => 1,
"number_of_replicas" => 0,
],
'mappings' => [
'articles' => \App\Article::mapping(),
],
],
]The document type, in this example articles must match searchableAs() for the respective model.
Elasticsearch can set default types to model fields on the first insert if you do not explicitly define them. However; sometimes the defaults are not what you're looking for, or you need to define additional mapping properties.
In that case, we strongly recommend creating indices with proper mappings before inserting any data.
For that purpose, there is an Artisan command, called elastic:make-indices {index} which creates an index based on
the settings in your configuration file.
To create all indices from your config just ignore the {index} parameter and run:
php artisan elastic:make-indices
If the index exists you will be asked if you want to delete and recreate it, or you can use the --force flag.
To get information about your existing Elasticsearch indices you may want to use the following command:
php artisan elastic:indices
You may follow instructions from the official Laravel Scout documentation to index your data.
The package supports everything that is provided by Laravel Scout.
The Scout search method used the default query method defined in the config file.
Sorting with orderBy() method:
$articles = Article::search($keywords)
->orderBy('id', 'desc')
->get();However, to use the extra Elasticsearch features included in this package, use trait ElasticSearchable
by adding it to your model instead of Searchable:
class Article extends Model
{
// use Searchable;
use ElasticSearchable;
// ...
}The package features:
- The
elasticSearchmethod,elasticSearch($method, $query, array $params = null):
$articles = Article::elasticSearch('multi_match', $q, [
'fields' => ['title', 'content', 'tags'],
'fuzziness' => 'auto',
'prefix_length' => 2,
'operator' => 'AND'
])->get();Parameters are taken from the configuration, for the specific query method, if not supplied. But you may override them.
- A separate Elasticsearch index for each model.
If you have defined several indices in your config file,
you may choose which index a model belongs to by overriding searchableWithin() method in your model:
public function searchableWithin()
{
return 'foobar';
}If you do not override searchableWithin() in your model, the first index from the config will be used.
