My mum and dad told me a story last week about my 18 year old nephew. He has learning difficulties and a mental age of about 7 or 8.
Anyway, he went on the Internet and was searching for model trains under the term, 'Hornby', a model train manufacturer, except he spelt it wrong and missed out the 'b'.
The poor lad was very puzzled wondering why he wasn't getting the images of trains he was expecting.
