Google-search – Visit m.google.com from regular computer

The query cache:url will display Google’s cached version of a web page, instead of the current version of the page. For example, [ cache:www.eff.org ] will show Google’s cached version of the Electronic Frontier Foundation home page.

Note: Do not put a space between cache: and the URL (web address).

However, when I try the web site you referred, Google does not open any cached version. That must be because Google has not been caching that site. However, it brings a cached version if you use cache:www.fotosite.pl instead of cache:raw.fotosite.pl.

This feature is not available in classic Google Search and it's not in Google's roadmap. You can learn more about this topic watching the Google video Will Google implement the ability to search with regular expressions?

However, there's one exception. Google Code Search supports regular expressions. Of course, the search target for this topic search engine is reduced to source code only.

It is worth to mention that some Google search keywords can partially replace regular expressions. For example, if you want to search any two-word variation of "search TERM", you can use the wildcard operator.

search *

will find results for search and any other (one) word. I often use it to check basic English grammar rules or synonyms (e.g., "as easy as *").
