In the aggregation pipeline, the $search stage is very helpful in developing my organization's application's functionalities. But using the Stable API or Versioned API, as it was once called, I am unable to use the $search stage as it is a part of Atlas Search and not a core MongoDB Server function. I would like to request that the support for Atlas Search be added to Stable API. This will allow my organization to seamlessly upgrade the server without breaking functionality. Other workarounds are not possible for us. Please do consider this as a feature for current or future versions of the Stable API.
