The following example initializes a Bulk() operations builder
for the items collection and adds a remove operation and an update
operation to the list of operations. The remove operation and the
update operation use the Bulk.find() method to specify a
condition for their respective actions:
var bulk = db.items.initializeUnorderedBulkOp(); bulk.find( { status: "D" } ).remove(); bulk.find( { status: "P" } ).update( { $set: { points: 0 } } ) bulk.execute();
