// Put a user/item assocation, here use #101 as an association of strength 0.5 with item #1000
$myrrix->setPreference(101, 1000, 0.5);

// Refresh the index
$myrrix->refresh();

// Get a recommendation for user #101
$recommendation = $myrrix->getRecommendation(101); // an array of itemId and strength (example: [[325,0.53],[98,0.499]])
