Laravel MySQL fulltext search

This package creates a MySQL fulltext index for models and enables you to search through those.

Requirements

• Laravel >= 5.7
• MySQL >= 5.6 / MariaDB >= 10.0.15

Important!

In config/database.php set

'mysql' => [
...
    'strict' => false,
...
]

Install

1. Install with composer composer require provision/searchable.
2. Publish migrations and config php artisan vendor:publish --tag=searchable
3. Migrate the database php artisan migrate

Usage

The package uses a model observer to update the index when models change. If you want to run a full index you can use the console commands.

Models

Add the SearchableTrait trait to the model you want to have indexed and define the columns you'd like to index as title and content.

Example

class Clients extends Model
{

    use \ProVision\Searchable\Traits\SearchableTrait;

    /**
     * @inheritDoc
     */
    protected function getSearchableTitleColumns(): array
    {
        return [
            'name'
        ];
    }

    /**
     * @inheritDoc
     */
    protected function getSearchableContentColumns(): array
    {
        return [
            'description',
            'address',
            'vat_number',
            'contacts.value',
            'contactPersons.first_name',
            'contactPersons.last_name',
            'contactPersons.contacts.value',
        ];
    }

}

You can use a dot notation to query relationships for the model, like contacts.value.

Relation model indexing

On related model for indexing use SearchableRelationTrait and method getSearchableRelationName to return relation name.

Listen for changes on relation and update parent model

Example

class Contact extends Model
{
    use \ProVision\Searchable\Traits\SearchableRelationTrait;

     /**
     * @return MorphTo
     */
    public function contactable()
    {
        return $this->morphTo();
    }

    /**
     * @inheritDoc
     */
    static function getSearchableRelationName(): string
    {
        return 'contactable';
    }
}

Searching

You can search using the search method.

$clientsCollection = Clients::search('John Doe')->paginate();

Search with specific fulltext search mode

use ProVision\Searchable\SearchableModes;
---
$clientsCollection = Clients::search('John Doe', SearchableModes::Boolean)->paginate();

Available modes

• NaturalLanguage - IN NATURAL LANGUAGE MODE
• NaturalLanguageWithQueryExpression - IN NATURAL LANGUAGE MODE WITH QUERY EXPANSION
• Boolean - IN BOOLEAN MODE
• QueryExpression - WITH QUERY EXPANSION

MySQL fulltext search documentation: https://dev.mysql.com/doc/refman/8.0/en/fulltext-search.html

Search with relations & additional wheres

$clientsCollection = Clients::search('John Doe')->where('active', 1)->with(['contacts'])->paginate();

Order searchable score

$clientsCollection = Clients::search('John Doe')->searchableOrder('asc')->paginate();

Available options:

• ASC
• DESC

Commands

searchable:index

php artisan searchable:index "\App\Models\Client" 1

searchable:unindex

UnIndex all models for a certain class

Usage:
  searchable:unindex <model_class> {id?}

Arguments:
  model_class           Classname of the model to index
  id                    Model id to unindex (optional)

Example

• UnIndexing all clients

php artisan searchable:unindex "\App\Models\Client"
