"Everywhere on the web users can search case insensitive, except when your site is based on a database like mongodb."

Where all users at the moment uses case insensitive everywhere, i think it is good that mongodb will support fast search on that on indexes as well as on full table scans. Even things like Ë can be find by searching just for e. If mongodb can handle this, this database can better be used daily.

So please provide a way so all searches are automatically be done in a case insensitive manner.
