Sphinx Search

Sphinx Search is a package for Laravel 4 which queries Sphinxsearch and integrates with Eloquent.

Installation

Add scalia/sphinxsearch to composer.json.

"scalia/sphinxsearch": "dev-master"

Run composer update to pull down the latest version of Sphinx Search.

Now open up app/config/app.php and add the service provider to your providers array.

'providers' => array(
	'Scalia\SphinxSearch\SphinxSearchServiceProvider',
)

Now add the alias.

'aliases' => array(
	'SphinxSearch' => 'Scalia\SphinxSearch\SphinxSearchFacade',
)

Configuration

To use Sphinx Search, you need to configure your indexes and what model it should query. To do so, publish the configuration into your app.

php artisan config:publish scalia/sphinxsearch

This will create the file app/config/packages/scalia/sphinxsearch/config.php. Modify as needed the host and port, and configure the indexes, binding them to a table and id column.

return array (
	'host'    => '127.0.0.1',
	'port'    => 9312,
	'indexes' => array (
		'my_index_name' => array ( 'table' => 'my_keywords_table', 'column' => 'id' ),
	)
);

Or disable the model querying to just get a list of result id's.

return array (
	'host'    => '127.0.0.1',
	'port'    => 9312,
	'indexes' => array (
		'my_index_name' => FALSE,
	)
);

Usage

Basic query (raw sphinx results)

$results = SphinxSearch::search('my query')->query();

Basic query (with Eloquent)

$results = SphinxSearch::search('my query')->get();

Query another Sphinx index with limit and filters.

$results = SphinxSearch::search('my query', 'index_name')
	->limit(30)
	->filter('attribute', array(1, 2))
	->range('int_attribute', 1, 10)
	->get();

Query with match and sort type specified.

$result = SphinxSearch::search('my query', 'index_name')
	->setFieldWeights(
		array(
			'partno'  => 10,
			'name'    => 8,
			'details' => 1
		)
	)
	->setMatchMode(\Sphinx\SphinxClient::SPH_MATCH_EXTENDED)
	->setSortMode(\Sphinx\SphinxClient::SPH_SORT_EXTENDED, "@weight DESC")
	->get(true);  //passing true causes get() to respect returned sort order

Query and sort with geo-distant searching.

$radius = 1000; //in meters
$latitude = deg2rad(25.99);
$longitude = deg2rad(-80.35);
$result = SphinxSearch::search('my_query', 'index_name')
	->setSortMode(\Sphinx\SphinxClient::SPH_SORT_EXTENDED, '@geodist ASC')
	->setFilterFloatRange('@geodist', 0.0, $radius)
	->setGeoAnchor('lat', 'lng', $latitude, $longitude)
	->get(true);

Integration with Eloquent

This package integrates well with Eloquent. You can change index configuration with modelname to get Eloquent's Collection (Illuminate\Database\Eloquent\Collection) as a result of SphinxSearch::search.

return array (
	'host'    => '127.0.0.1',
	'port'    => 9312,
	'indexes' => array (
		'my_index_name' => array ( 'table' => 'my_keywords_table', 'column' => 'id', 'modelname' => 'Keyword' ),
	)
);

Eager loading with Eloquent is the same an one would expect:

$results = SphinxSearch::search('monkeys')->with('arms', 'legs', 'otherLimbs')->get();

Paging results in Laravel 4 (with caching)

Route::get('/search', function ()
{
    $page = Input::get('page', 1);
    $search = Input::get('q', 'search string');
    $perPage = 15;  //number of results per page
    // use a cache so you dont have to keep querying sphinx for every page!
    $results = Cache::remember(Str::slug($search), 10, function () use($search)
    {
        return SphinxSearch::search($search)
        ->setMatchMode(\Sphinx\SphinxClient::SPH_MATCH_EXTENDED2)
        ->get();
    });
    if ($results) {
    	$totalItems = $results->count();
        $pages = array_chunk($results->all(), $perPage);

        $paginator = Paginator::make($pages[$page - 1], $totalItems, $perPage);
        return View::make('searchpage')->with('data', $paginator);
    }
    return View::make('notfound');
});

Paging results in Laravel 4 (without caching)

Route::get('/search', function ()
{
    $page = Input::get('page', 1);
    $search = Input::get('q', 'search string');
    $perPage = 15;  //number of results per page
    $items = null;

    $results = SphinxSearch::search($search)
        ->setMatchMode(\Sphinx\SphinxClient::SPH_MATCH_EXTENDED2)
        ->limit($perPage, ($page-1)* $perPage)
        ->get();

    if (!empty($results['total'])) {
        $items = Item::whereIn('id', array_keys($results['matches']))->get();
        $items = Paginator::make($items->all(), $results['total'], $perPage);

        $items->appends(['search' => $search]); //add search query string
    }

    if($error = SphinxSearch::getErrorMessage())
    {
        // 
    }
});

And, in your view after you finish displaying rows,

<?php echo $data->links()?>

Searching through multiple Sphinx indexes (main/delta)

It is a common strategy to utilize the main+delta scheme (www.sphinxconsultant.com/sphinx-search-delta-indexing/). When using deltas, it is often necessary to query on multiple indexes simultaneously. In order to achieve this using SphinxSearch, modify your config file to include the "name" and "mapping" keys like so:

return array (
	'host'    => '127.0.0.1',
	'port'    => 9312,
	'indexes' => array (
	    'name'    => array ('main', 'delta'),
	    'mapping' => array ( 'table' => 'properties', 'column' => 'id' ),
	)
);

You can also pass in multiple indexes (separated by comma or space) to your search like so (if the "mapping" key is not specified in the config, search retrieves ids):

SphinxSearch::search('lorem', 'main, delta')->get();

Retrieve search result excerpts using Sphinx

It is nifty to display excerpts with keywords highlighted in search result. Sphinx supports this feature natively. http://sphinxsearch.com/docs/archives/2.0.3/api-func-buildexcerpts.html

$search = SphinxSearch::search($term, 'articles');
$articles = $search->get();
$excerpt = $search->excerpt(current($articles)->content);

or

$search = SphinxSearch::search($term, 'articles');
dd($search->excerpts(array_pluck($articles, 'content')));
