> Ability to define hierarchical trait types and ability to search metadata by tags that considers the hierarchy of trait definitions are very useful for defining tag based policies (ex: security policies). As per my experience, the search with tags is not completely implemented when there are hierarchy of trait definitions.
> It seems search by tags follow the OO polymorphism and works as follows:
> - If you search metadata by super trait, it will return the metadata that are tagged by the given super trait and all its sub-traits.
> - If you search metadata by a sub-trait, it will return the metadata that are tagged by the given sub-trait only.
> For example, I have 2 traits: 
> "archived" is sub-trait of "frozen"
>  - The metadata can go into frozen state (not archived). And, when the metadata is archived it means it is also frozen.
> search?query=archived
> - Returns all metadata instance IDs that are tagged with "archived" only
> search?query=frozen
> - Returns all metadata instance IDs that are tagged with both "frozen" and its sub-trait, "archived"
> But, if I want to retrieve metadata of a given type by using the tags, it does not work as expected.
>  
> search?query=Account is archived
> search?query=from Account where (Account is archived) 
> - Returns Accounts that are tagged with "archived" only as expected
> search?query=Account is frozen
> search?query=from Account where (Account is frozen) 
> - I would expect the Accounts that are tagged by both "frozen and "archived". But, it returns Accounts that are tagged with frozen only
