Aggregating

The Basics

Make an index and add a few documents to it:

use Ehann\RediSearch\Index;

$bookIndex = new Index($redis);

$bookIndex->add([
    'title' => 'How to be awesome',
    'price' => 9.99
]);

$bookIndex->add([
    'title' => 'Aggregating is awesome',
    'price' => 19.99
]);

Now group by title and get the average price:

$results = $bookIndex->makeAggregateBuilder()
    ->groupBy('title')
    ->avg('price');
