Can't find Problem #278 (Polyomino Generation) through Search

[Alena-Stavrova]

I was trying to find the Problem #278 (Polyomino Generation) in Search with the keyword "polyomino" or "polyominoes" but it either doesn't show you any results or gives you a link to the Problem #285 (Rotate Matrix in Place) where the Polyomino problem is mentioned. Technically, the Problem #285 does have a link to the Problem #278, so it is kind of a workaround. But the Search doesn't give you a direct link to the Problem #278.

The keyword "polyomino generation" gives you a direct link to the Problem #278, but it's likely that most users will try a shorter search phrase.

That's much interesting, thank you :) Search is provided by 3rd party (Yandex) and I understand it got messed because problem link was changed after typo was found... But it's really interesting whether it is possible to make yandex update its index... I'll have a look at it!
