This package makes it easy to use native PostgreSQL Full Text Search capabilities with Laravel Scout:

// plainto_tsquery()
$posts = App\Post::search('cat rat')
    ->usingPlainQuery()->get()

// phraseto_tsquery()
$posts = App\Post::search('cat rat')
    ->usingPhraseQuery()->get()

// to_tsquery()
$posts = App\Post::search('fat & (cat | rat)')
    ->usingTsQuery()->get()

// websearch_to_tsquery()
// uses web search syntax
$posts = App\Post::search('"sad cat" or "fat rat" -mouse')
    ->usingWebSearchQuery()->get()

// DIY using a callback
use ScoutEngines\Postgres\TsQuery\ToTsQuery;

$results = App\Post::search('fat & (cat | rat)', function ($builder, $config) {
    return new ToTsQuery($builder->query, $config);
})->get();

And here's an example model:

class Post extends Model
{
    use Searchable;

    // Configurable search data...
    // Bring other data (i.e., tags) to the index document
    public function toSearchableArray()
    {
        return [
            'title' => $this->title,
            'content' => $this->content,
            'author' => $this->user->name,
            'tags' => $this->tags->pluck('tag')->implode(' '),
        ];
    }

    public function searchableOptions()
    {
         return [
            // Model search config for index settings, rank, etc.
         ];
    }
}

The way this integration works is that the parsed document model data is stored in the same table in the searchable column with the tsvector type. You can fine-tune how each model works by integrating a searchableOptions() method, which allows you to:

• Configurable column name (default is searchable)

• Rank groups can be assigned to fields in the table

• Rank weights are configurable for each rank group

• Configurable ranking function to use (ts_rank or ts_rank_cd)

• Rank normalization

• And more...
