During T219364 users were not able to use entities that they created for a rough 24 hour period.

11:03 AM <+gehel> lag of multiple hours is unexpected and **should** not happen (or if it does, it should be treated as a bug)
11:04 AM <+gehel> but lag of < 1h is perfectly normal

We should consider using a combined search again allowing users to use entities that they create moments after creating them rather than needing to worry about cirrus search lag.
We could also consider some clever JS that when just and entity id is entered, detect this somehow and allow the user to try sending the edit request which would then be validated on the server side?
We could also have some sort of fallback if we detect that the cirrus search returned no results and is lagged?
