Recently, Facebook removed from their API the ability to search for pages, so we made a few changes in order to adapt to their new restrictions.
If the page you are looking for does not appear in the search results, that means that it's not in our database. For it to appear in the results, try copying and pasting the Facebook url. For example:
If that does not work, the page you are trying to analyze most likely has some restrictions in place (is not published or has country/age restrictions). If you can see the page on Facebook, try logging in and search for it again.
Even if it doesn't appear in the results, you can still analyze it by clicking in the url (see here for more information on how to do it).
