The "Google test" used to be a tool for checking the notability of a subject or to find sources about it. For some languages it may be also used for other purposes - for example in Hebrew, the spelling of which is not established so well, it is very frequently used for finding the most common spelling, especially for article titles. It was never the ultimate tool, of course, but it was useful. With the proliferation of sites that indiscriminately copy Wikipedia content it is becoming less and less useful.
For some time i used to fight this problem by adding "-site:wikipedia.org-site: wapedia.mobi -site:miniwiki.org" etc. to my search queries, but i hit a wall: Google limits the search string to 32 words, and today there are many more than 32 sites that clone Wikipedia, so this trick is also becoming useless.
I know that some Wikipedias customized Special:Search, adding other search engines except Wikipedias built-in one. I tried to see whether any Wikipedia added an ability to search using Google (or Bing, or Yahoo, or any other search engine) excluding Wikipedia clones. Does anyone know whether it's possible to build such a thing? And maybe it already exists and i didn't search well enough?
