Making minimal changes to your code to allow it compile here, and it simply never finds anything(very quickly), no matter how simple I make the search criteria:

I've wasted enough time on it; and won't be expending any more, but here is the modified code that compiles clean (apart from warnings that originate from your posted code):

I'd suggest you enter it in an obfuscated C competition; could be a winner.

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority". I'm with torvalds on this

In the absence of evidence, opinion is indistinguishable from prejudice. Agile (and TDD) debunked
