Dear BrowserUk,

I ran your search subroutine on some hard data, three 'needles', and three different 'haystacks'. I realised that you didn't set a lower limit of consecutive matches, as you'll see from the output below, it even matches when just the first letter of the needle matches the last letter of the haystack.

I was going to try and edit your code myself, but the collection of return statements had me confused, so I was wondering, what would you do to your code to set that lower limit, which should probably be a higher number, like 6, now that I think about it.

Cheers
Sam
