How to use aggregation

[Edvinaz]

Sorry if I missed answer somewhere, but I cant solve one issue...

I build query from many filters and I need to get count of documents distincted by two columns. Distinct and group by seems not working... With raw aggregation I get what i need, but question is how to build aggregation if my $match stage is build with Builder

You can't mix the query builder and raw aggregation. An aggregation builder will be created to solve this issue.

The current way to use custom aggregation is like this:

use MongoDB\Collection;

$builder->raw(function (Collection $collection) {
    return $collection->aggregate($pipeline, $options);
});
