Solarium compilation target for RulerZ

Solarium compilation target for RulerZ.

Usage

solarium/solarium is one of the targets supported by RulerZ. It allows the engine to query an Solr server.

This cookbook will show you how to retrieve objects using solarium/solarium and RulerZ.

Here is a summary of what you will have to do:

• configure solarium;
• configure RulerZ;
• filter your target.

Configure solarium

This subject won't be directly treated here. You can either follow the official documentation or use a bundle/module/whatever the framework you're using promotes.

Configure RulerZ

Once solarium/solarium is installed and configured we can the RulerZ engine:

$rulerz = new RulerZ(
    $compiler, [
        new \RulerZ\Solarium\Target\Solarium(), // this line is Solarium-specific
        // other compilation targets...
    ]
);

The only Solarium-related configuration is the Solarium target being added to the list of the known compilation targets.

Filter your target

Now that both solarium/solarium and RulerZ are ready, you can use them to retrieve data.

The Solarium instance that we previously injected into the RulerZ engine only knows how to use Solarium\Client objects, so the first step is to create one:

$config = [
    'endpoint' => [
        'localhost' => [
            'host' => '127.0.0.1',
            'port' => 8983,
            'path' => '/solr/',
        ]
    ]
];
$client = new \Solarium\Client($config);

And as usual, we call RulerZ with our target (the \Solarium\Client object) and our rule. RulerZ will build the right executor for the given target and use it to filter the data, or in our case to retrieve data from Solr.

$rule  = 'gender = :gender and points > :points';
$parameters = [
    'points' => 30,
    'gender' => 'M',
];

var_dump(
    iterator_to_array($rulerz->filter($client, $rule, $parameters))
);
