laravel-searchable

Make Laravel models instantly searchable, and automatically indexed using Elastic Search.

Work in progress

Adding search functionality to a laravel model only requires using a trait. Using the SearchableTrait in your modle will enable a model observer that acts on the created, updated and deleted events to keep your indexes up to date.

The trait adds a search method to your model that makes it easy to search Elastic Search for hits.

The provided facade allows similar functionality, and the added ability to search in multiple document types (i.e. models) at once.

Installation

Composer

Include the package in your composer file, and run composer update.

I'm still working on this, but dev-master will change to a stable tag as soon as I have one ready.

{
  "require" : {
     ...
    "wkjagt/searchable": "dev-master"
  }
}

Service provider

Add the ServiceProvider to your app.php:

'providers' => [
    ...
    'Searchable\SearchableServiceProvider'
]

Searchable Facade

If you want to use the Searchable facade, add it to your aliases in app.php:

'aliases' => [
    ...
    'Searchable'      => 'Searchable\SearchableFacade'
]

Searchable Trait

Add the SearchableTrait to the models you want indexed. For example:

class Thing extends Model {

    use SearchableTrait;
    
    ...
}

That's all you need to get started. Newly created Thing models will be automatically indexed. By default, all models will be added to a default index, and the fully qualified class name will be used as the document type (where backslashes are replaced by dots). This is fine for normal usage, but can be modified by adding static properties to your model:

class Thing extends Model {

    use SearchableTrait;
    
    public static $searchDocumentType = 'thing';
    
    public static $searchIndexName = 'my_index';
}

Searching

Searching can be done in two ways. SearchableTrait adds a search method to your model, which accepts one argument: an Elastic Search query. For example:

$query = [ 'filtered' => [
    'query' => [ 'match' => [ 'name' => 'some_name' ]],
    'filter' => [ 'term' => [ 'user_id' => 14 ]],
]];

$hits = Thing::search($query);

You can also search multiple models at once using the Searchable facade, which uses the native Elastic Search way of searching in multiple indexes/document types. The search method on Searchable takes an array of fully qualified class names of models, and needs to be chained to the withSearch method. An example:

$query = [ 'filtered' => [
    'query' => [ 'match' => [ 'name' => 'some_name' ]],
    'filter' => [ 'term' => [ 'user_id' => 14 ]],
]];

$hits = Searchable::search(['Thing', 'OtherThing'])->withQuery($query);

The results are returned as an array of Searchable\SearchResult instances, which are simple value objects, with two public properties:

  • hit: a hydrated Laravel Model
  • score : the search score

Indexing existing models

When adding Searchable to an existing project, you probably want to index your existing models. The added searchable:indexall artisan command adds this functionality to each model that uses SearchableTrait. To index all resources for a given model, run the command, passing the fully qualified class name as argument, replacing any backslashes with forward slashes:

./artisan searchable:indexall Namespace/Of/Your/Model
