Google (GOOG) is testing a new version of Google Websearch at www2.sandbox.google.com, and they want you to give them feedback on the quality of results.
Matt Cutts of Google says:
“The Caffeine update isn’t about making some UI changes here or there. Currently, even power users won’t notice much of a difference at all. This update is primarily under the hood: we’re rewriting the foundation of some of our infrastructure. But some of the search results do change, so we wanted to open up a preview so that power searchers and web developers could give us feedback.”
The Webmaster Central Blog says this about the feedback:
“Do a search at http://www2.sandbox.google.com/ and look on the search results page for a link at the bottom of the page that says “Dissatisfied? Help us improve.” Click on that link, type your feedback in the text box and then include the word caffeine somewhere in the text box.”
The default search is in English. You can change the URL to generate results for other languages. Change these two values:
hl = language
gl = country code
Examples:
German language in Germany: &hl=de&gl=de
http://www2.sandbox.google.com/search?hl=de&gl=de&q=alle+meine+entchen
Spanish language in Mexico: &hl=es&gl=mx
http://www2.sandbox.google.com/search?hl=es&gl=mx&q=de+colores
Include the word “caffeine” somewhere in the feedback.
Face search engine Facesærch (yepp, that’s the way they spell it) has made a search interface called Google Caffeine Compare, which lets you generate two search engine result pages from the same search form, one for Google Caffeine and one for the regular Google Web Search.
