Specifies a query condition for an update or a remove operation.

Bulk.find() accepts the following parameter:

Parameter
Type
Description
query
document

Specifies a query condition using Query Selectors to select documents for an update or a remove operation. To specify all documents, use an empty document {}.

With update operations, the sum of the query document and the update document must be less than or equal to the maximum BSON document size.

With remove operations, the query document must be less than or equal to the maximum BSON document size.

Use Bulk.find() with the following write operations:

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" } ).delete();
bulk.find( { status: "P" } ).update( { $set: { points: 0 } } )
bulk.execute();
