Google and my intelligence; one brief study of a peculiar inverse relationship

So, in the process of trying a C. K. Williams emulation, I wanted to use the word "concavance" in my poem and I could not, in good conscience, avoid a quick search for the word usage. A Google query returned 3 hits (5 if you count omitted results). Now, I digress. That must -- MUST -- be the lowest number of hits received for a single, actual(?) word put into the search field. I digress again -- Two summers ago during my stay with the Xerox family in the employee wing, I would "play" a Google show-off of sorts with my coworker. We'd think of word combinations to put into Google and whoever got the lowest number of hits for their phrase "won". It was hard times in the summer of 2005...But Word Nerds always find amusement, it seems.

Well, back to "concavance" -- so I queried. And it led me to a link on FreshPatents.com. A search from the homepage of the aforementioned dotcom led me to this new pending-patent idea. Ah yes, it seems the world IS incomplete without flavored straws.

And this all still didn't resolve my original dilemma. Is "concavance" even a credible word? I guess I should go with "concaveness"??
