search stages such as $search, $searchMeta, and $vectorSearch used to return empty results for timeseries collections. This ticket changed the behavior and now $search, $searchMeta, and $vectorSearch will fail with the error message "<stage name> is unsupported for timeseries collections" if run on a timeseries collection.

Description of Linked Ticket

We should block stages that should never run on timeseries collections from running on timeseries collections. We can do this by adding a new stage constraint to certain document sources. $search stages cannot run on timeseries collections and should be validated through a stage constraint.

Separate but related tickets are filed for the following stages because they need a different implementation

• $rankFusion pipelines
• $merge target collection. The source collection can be a timeseries collection, but the $merge.into collection cannot be a timeseries collection
• change streams
