An aggregation pipeline can be used to represent a query, like the following:
db.example.aggregate([{$project: {excluded: 0}}, {$match: {predicate: true}}]);
In these cases, it would be more efficient to skip the aggregation layer, and execute the entire computation using a query.
It is expected that pipelines like the above pipeline will be much more common once non-materialized views are introduced in SERVER-142.
