Official news on crawling and indexing sites for the Google index
Help test some next-generation infrastructure
lunedì, agosto 10, 2009
Webmaster Level: All
To build a great web search engine, you need to:
Crawl a large chunk of the web.
Index the resulting pages and compute how reputable those pages are.
Rank and return the most relevant pages for users' queries as quickly as possible.
For the last several months, a large team of Googlers has been working on a secret project: a next-generation architecture for Google's web search. It's the first step in a process that will let us push the envelope on size, indexing speed, accuracy, comprehensiveness and other dimensions. The new infrastructure sits "under the hood" of Google's search engine, which means that most users won't notice a difference in search results. But web developers and power searchers might notice a few differences, so we're opening up a web developer preview to collect feedback.
Some parts of this system aren't completely finished yet, so we'd welcome feedback on any issues you see. We invite you to visit the web developer preview of Google's new infrastructure at
http://www2.sandbox.google.com/
and try searches there.
Right now, we only want feedback on the
differences
between Google's current search results and our new system. We're also interested in higher-level feedback ("These types of sites seem to rank better or worse in the new system") in addition to "This specific site should or shouldn't rank for this query." Engineers will be reading the feedback, but we won't have the cycles to send replies.
Here's how to give us 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. Thanks in advance for your feedback!
Update on August 11, 2009: [
If you have language or country specific feedback on our new system's search results, we're happy to hear from you. It's a little more difficult to obtain these results from the
sandbox URL
, though, because you'll need manually alter the
query parameters
.
You can change these two values appropriately:
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
And please don't forget to add the word "caffeine" in the feedback text box. :)
