我正在尝试删除一堆具有共同属性的文档。这是文档的样子:{_id:{attr1:'foo',attr2:'bar'},attr3:'baz',}多个文档在attr1条目中将具有相同的“foo”值。我正在尝试删除所有这些。为此，我有类似的东西:typeDocIdstruct{Attr1string`bson:"attr1,omitempty"`Attr2string`bson:"attr2,omitempty"`}typeDocstruct{IdDocId`bson:"_id,omitempty"`Attr3string`bson:"attr3,omitempty"`}doc:=Doc{I

我正在查询一个包含嵌套项目数组的json结构。我想返回整个结构，但只包括符合查询条件的嵌套项目。所以-样本结构是{parentId:1,items:[{field1:1field2:2},{field1:3field2:4}]}我想查询这样的东西->db.getCollection('mycollection').find({"items.field1":1,"items.field2":2})这行得通，但它也带回了第二个子项，我希望它实际返回的是这个->{parentId:1,items:[{field1:1field2:2}]}我已经能够在MongoDB本身中创建一个查询，它实现了
