This is an opinionated Laravel 5.1 package to store and retrieve objects from a search index. Currently Elasticsearch and Algolia are supported.
Once the package is installed objects can be easily indexed and retrieved:
//$product is an object that implements the Searchable interface
SearchIndex::upsertToIndex($product);
SearchIndex::getResults('look for this');Spatie is a webdesign agency in Antwerp, Belgium. You'll find an overview of all our open source projects on our website.

This package can be installed through Composer.
composer require spatie/searchindexYou must install this service provider.
// config/app.php
'providers' => [
...
Spatie\SearchIndex\SearchIndexServiceProvider::class,
];This package also comes with a facade, which provides an easy way to call the the class.
// config/app.php
'aliases' => [
...
'SearchIndex' => Spatie\SearchIndex\SearchIndexFacade::class,
]You can publish the config-file with:
php artisan vendor:publish --provider="Spatie\SearchIndex\SearchIndexServiceProvider"The options in the config file are set with sane default values and they should be self-explanatory.
The next installation steps depend on if you want to use Elasticsearch or Algolia.
To use Elasticsearch you must install the official 1.x series low level client:
composer require elasticsearch/elasticsearch "^1.3"You also should have a server with Elasticsearch installed. If you want to install it on your local development machine you can use these instructions from the excellent Vaprobash repo.
To use Algolia you must install the official low level client:
composer require algolia/algoliasearch-client-phpObjects that you want to store in the index should implement the
provided Spatie\SearchIndex\Searchable- interface.
namespace Spatie\SearchIndex;
interface Searchable {
/**
* Returns an array with properties which must be indexed
*
* @return array
*/
public function getSearchableBody();
/**
* Return the type of the searchable subject
*
* @return string
*/
public function getSearchableType();
/**
* Return the id of the searchable subject
*
* @return string
*/
public function getSearchableId();Here is an example how you could implement it with an Eloquent model:
class Product extends Eloquent implements Searchable
{
...
/**
* Returns an array with properties which must be indexed
*
* @return array
*/
public function getSearchableBody()
{
$searchableProperties = [
'name' => $this->name,
'brand' => $this->brand->name,
'category' => $this->category->name
];
return $searchableProperties;
}
/**
* Return the type of the searchable subject
*
* @return string
*/
public function getSearchableType()
{
return 'product';
}
/**
* Return the id of the searchable subject
*
* @return string
*/
public function getSearchableId()
{
return $this->id;
}
}The searchindex will use the returned searchableType and searchableId to identify an object in the index.
If you are using the facade it couldn't be simpler.
//$product is an object that implements the Searchable interface
SearchIndex::upsertToIndex($product);You probably would have guessed it.
//$product is an object that implements the Searchable interface
SearchIndex::upsertToIndex($product);Yep. Easy.
//$product is an object that implements the Searchable interface
SearchIndex::removeFromIndex($product);Alternatively you can remove an object from the index by passing type and id:
SearchIndex::removeFromIndexByTypeAndId('product', 1);This can be handy when you've already deleted your model.
If only you could to this with your facebook account.
SearchIndex::clearIndex();You can retrieve search results with this method:
SearchIndex::getResults($query);$query should be an array that adheres to the scheme provided
by the elasticsearch documentation.
A query to perform a fuzzy like search that operates all fields of the index could look like this:
$query =
[
'body' =>
[
'from' => 0,
'size' => 500,
'query' =>
[
'fuzzy_like_this' =>
[
'_all' =>
[
'like_text' => 'look for this',
'fuzziness' => 0.5,
],
],
],
]
];The search results that come back are simply elasticsearch response elements serialized into an array. You can see an example of a response in the official elasticsearch documentation.
You can just pass a string to search the index:
SearchIndex::getResults('look for this');To perform more advanced queries an array may be passed. Read the official documentation to learn what's possible.
For all other operations you can get the underlying client:
SearchIndex::getClient(); // will return the Elasticsearch or Algolia client.If you're using Algolia you can use a SearchQuery-object to perform searches.
use Spatie\SearchIndex\Query\Algolia\SearchIndex();
$searchQuery = new SearchQuery();
$searchQuery->searchFor('my query')
->withFacet('facetName', 'facetValue');
//a searchQuery object may be passed to the getResults-function directly.
SearchIndex::getResults($searchQuery);This package comes with a set of unit tests. Every time the package gets updated Travis CI will automatically run them.
You can also run them manually. You'll have first run composer install --dev to install phpspec. After that's out of the way you can run the tests with vendor/bin/phpspec run.
