No longer a legal word because Google has abandoned their earlier policy of "Don't Be Evil".
"Late last year, the Swedish Language Council published a report of words that had entered the Swedish lexicon in 2012. Among them was ogooglebar – ungoogleable, in English. This did not please Google."
adj. 1) failing to return results from a search engine, especially google.
2) effectively anonymous in the context of a google search (or similar search) due to the overwhelming number of high-ranking results produced by something/someone else with the same name.
(1) "To be ungoogleable is to have never existed" or (2) to have a very, very common name, like my baby sister: searching on her name yields “Results 1 - 10 of about 5,180.” even if she was there, it’d take me half of forever to find her. - Elaine Nelson
Having a name so common that a Google search yields thousands of different people with the same name, rendering the search pointless and thus shielding one from scrutiny.
when google takes a subject it thinks is to important for you. then takes the liberty to exclude it from your search results. thereby making it ungoogleable.
1) Information and intelligence that google™ are unable to pick up i.e. not a part of the googable world = ungoogable
2) A thing or event that you can't define the nature of.
3) An experience or feeling that you can't recreate.
a word, phrase, name, person, place, or thing that is unable to be found on google, which means that it probably doesn't exist or is so rare that people are not responsible for knowing it exists, yet.
What you're referring to is ungoogleable; therefore, if it actually is true you can't call us dolts for not knowing it.
That professor you speak of is ungoogleable, so I doubt the credibility of your claims.
