Regarding “Right to be Forgotten”, what's the definition of a “search engine”?

Question

§§ — The decision by Europe's highest court allows people living in Europe to ask for links to "inadequate, irrelevant or no longer relevant" material to be removed from search results, although it will still be available on the original web page[.]

Google Search might be unambiguously considered as a "search engine", but what about other websites like Blogger, Facebook, Twitter, Instagram, Quora, StackExchange, 4chan, Reddit, etc?

Are news websites which store their own archives of old news considered a "search engine", or "original web page", or both? (Notice that material must be removed from search results yet is allowed to remain available on the original web page.)

Let's assume that John Doe (either an imaginary student, salaryman, politician, etc) exercised his right to be forgotten. Then, :

• Does a blogger have the right to list links and prior search results of John Doe's past on his personal blog which is publicly available?

• If the blogger also writes about John Doe's past (i.e. the blogger creates original material), would the blogpost now be considered "original web page" and allowed to be available?

Answer 1

The judgment (Google Spain and Google (Judgment of the Court) [2014] EUECJ C-131/12) is definitive on this point at paragraph 41:

...the activity of a search engine consisting in finding information published or placed on the internet by third parties, indexing it automatically, storing it temporarily and, finally, making it available to internet users according to a particular order of preference...

In your example, the blogger would be unaffected by the decision as his links are presumably collected and sorted by hand. However, the blog itself may be removed from Google et al at the request of John Doe.
