To use $text in the $match stage, the $match stage has to be the first stage of the pipeline.You cannot use $near or $nearSphere in $match queries as part of the aggregation pipeline.You cannot use $where in $match queries as part of the aggregation pipeline.To include an aggregation expression in $match, use a $expr query expression. Because $match limits the total number of documents in the aggregation pipeline, earlier $match operations minimize the amount of processing down the pipe. You can place the $match as early in the aggregation pipeline as possible. $match takes a document that specifies the query conditions. The $match stage filters the documents to pass only the documents that match the specified condition(s) to the next pipeline stage. If you want to filter documents using _id field in the aggregate pipeline, you can use the $match stage. In MongoDB compass, you can use the filter field in UI to find a document by _id field. Compass asks for confirmation that you want to remove the document: Once you confirm, Compass deletes the document from the collection. After you click the delete button, the document is flagged for deletion. ![]() y = ObjectId("507f191e810c19729de860ea")Īlternatively, you can specify any other value to the _id field. To delete a document, hover over the document and click the icon. You can also specify a 24-character hexadecimal string value explicitly for the ObjectId. ObjectID can be considered globally unique across all documents. The _id field contains a unique ObjectID value.īy default when inserting documents in the collection, MongoDB automatically generates and assigns ObjectId to the _id field of each document. ![]() In MongoDB, _id field reserved as the primary key for the collection so that we can uniquely identify each document in the collection.
