Odd Search Strings

[MadMax]

I regularly see some odd search strings in my stats as the strings I turned up in the results for, like "10943399162078165." I see them halfway regularly, but never more than once or twice for any given string. Anyone know where these come from or what they represent?

If you have access to your raw logs you can do a search for that text to uncover which SE it is.
