Major Description
The documentation bug shows create meta().id is the only supported index type.
I can however create indexes on cas, flags and expiry - this should be blocked?
cbq> create index meta_3 on default(meta().cas);

The above select meta().cas shows {} empty results however, making this whole query non-functional?
