Question

I want to get all products by rating filter. here my code

$getProducts = $objectManager->create('Magento\Catalog\Model\ResourceModel\Product\Collection');
$getProducts->addAttributeToSelect('*');
$getProducts->addAttributeToFilter('visibility', 4);

So, how can I add here filter for rating so I need not to first get all product and then check all product with that rating issue.

You can try the below code for filter product collection by rating percent:

$collection = $_objectManager->create('Magento\Catalog\Model\ResourceModel\Product\Collection');
$collection->addAttributeToSelect('*');

$collection->getSelect()->joinLeft(array('rova'=> 'rating_option_vote_aggregated'),'e.entity_id =rova.entity_pk_value', array("percent" => 'percent'))->group('e.entity_id');

$collection->getSelect()->where("rova.percent = 80");

foreach($collection as $product){
    //YOUR CODE
}

100 Percent = 5 Star Rating

90 Percent = 4.5 Star Rating

80 Percent = 4 Star Rating

and so on...
