$sort

The sort stage take all documents it receives and passes them into the next stage in the specified sort order.

{"$sort": {<property1>: <sort order>, <property2>: <sort order>, ...}}

Where sort order can be 1 for ascending or -1 for descending.

Performance Considerations

To optimize performance, it is best to use $sort at the beginning of the pipeline or near the beginning, after a $match and $limit. And $sort should always proceed $project, $unwind, or $group if it is required -- otherwise your query may be slow or time out.

Examples

Example

GET /c_patients?pipeline=[{"$match": {"c_gender": "f"}},{"$limit": 2},{"$sort": {"c_name.c_last": 1},{"$project": {"c_name": 1}}}]
