People can restrict their search (Special:Search) to the Property and Lexeme namespaces by prefixing their search with P: and L: respectively. We don't have the same for EntitySchema. We should. We want to use E: as the shortcut.
GIVEN a search term prefixed with "E:"
WHEN executing the search via Special:Search
THEN the search is restricted to the namespace for Entity Schemas
- searches with "E:" are restricted to the Entity Schema namespace
- technically this seems to be realized by making E an alias for the Entity Schema namespace.
