The drawback to that approach is that you end up with ridiculously long entity names, like “Department name - Client name - Project Name - Task Type - Task name”. And they won’t be fully visible in many views like Tables.
Additionally, every time you realize there’s another field that you need indexed for that DB, you need to add it to the name, and it gets even more unwieldy.
More-complete indexing and more-intelligent search results ranking and presentation are a much more solid solution IMO.
