Hi Chris
Glad you found it. I think it's a good find. Thanks. I'll bet there's lots I miss, and a lot I don't search for, like personal names or band names. I really don't have any favorite heroes to search for. From the date stamp on the video, I'll bet it was put up on YouTube after I made my post. Would I have found it for next week? It's hard to say. I have found, sometimes, it takes as much as 48 hours for the Google and/or YouTube indexing system to show up on my computer in a search. It actually showed up Saturday evening here in Western PA, USA. It's weird in that it's not consistent. There are occasions, where I'll come across a video in the UK before it shows up in a search from Google.co.uk too. I've used both occasionally.
One of the biggest deterrents to a search has been around for a while. It's called a "filter bubble" and "localization" or personalization. If you and I were sitting next to each other and at the same time searched for something called "concertina" both computers would produce different results. Here's something worthwhile from last year on the issue:
There are also some strange results. It wants to return "concert in a ...", concertino, and some other strange things, but won't return "konsertina" and language variations.
There are a few work arounds that only just barely help, but, the old "world wide" searches are no more. Google is not necessarily "your friend", and I haven't been able to find a good replacement. At least it's familiar.
Keep finding them. There're many "crooks and nannies" for them to hide.
Thanks
Leo
