Example queries have incorrect casing

[GuiltyDolphin]

The example queries appear to be uc'd on each first word - which can lead to misleading or invalid queries (you should be able to manually type in the shown query), for example:

Becomes

Which is not the same!

I think perhaps it would be best to just display the queries in the same case they were entered?
