One (full) word documented here
So that searches are by full words is mentioned in a post, but not it's not mentioned, until this current thread, what the word delimiter characters are. That is, are
words consecutive sequences of alphanumeric characters, or are they consecutive sequences of non-white-space characters.
And the only way, the only way, to find this documentation is to get TomServo on you case for missing (in this case, despite trying hard) previous posts, then ask him?
Time I submitted a couple of suggestions to the admins.
You have been helpful, sir. Thank-you. Nevermind my grumpiness.
