To build a great web search engine, you need to:
  1. Crawl a large chunk of the web.
  2. Index the resulting pages and compute how reputable those pages are.
  3. 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. :) ]

salam every one, this is a topic from google web master centrale blog:
Recently we mentioned some updates in the Webmaster Tools GData API: we've just launched a whole new API, the Message Center GData API, as part of the Webmaster Tools API. The Message Center is the way that Google communicates to webmasters important issues regarding their sites—for example, if there's a problem crawling your site, or if someone has requested a change in crawl rate. Until now it was only possible to access these messages through the Message Center section of Webmaster Tools; but now you can also use GData to access it as a feed. This way you don't need to continually check your messages in Webmaster Tools, you can retrieve the messages feed automatically and be informed as soon as possible of any critical issues regarding your site.
What can I do?
The Message Center GData API lets you retrieve all messages, mark the messages as read or unread, and delete messages. You can do these tasks using the provided Java client libraries, or you can create your own client code based on the protocol information.
  • Retrieve messages: The messages feed contains all the messages sent to your account. These messages have important information about your verified sites. Examples of messages include infinite spaces warnings and crawl rate change notifications.
  • Mark messages as read or unread: In order to keep track of new communications from Google, you can mark your messages as read or unread, the same way that you would manage your inbox. If you retrieve a single message, this message will be automatically marked as read.
  • Delete mesages: It's possible to delete messages using the GData API. However, be careful because if you delete a message through the API it will also be deleted in your Webmaster Tools account, as both interfaces share the same data.
How do I do it?
You can download code samples in Java for all these new features. These samples provide simple ways to use the messages feed. The following snippet shows how to retrieve the messages feed in a supported language and print all the messages:
  // Connect with the service and authenticate
  WebmasterToolsService service
      = new WebmasterToolsService("exampleCo-exampleApp-1");
  try {
    service.setUserCredentials(USERNAME, PASSWORD);
  } catch (AuthenticationException e) {
    System.out.println("Username or password invalid");
    return;
  }
  // Retrieve messages feed
  MessagesFeed messages;
  try {
    URL feedUrl;
    if (USER_LANGUAGE == null) {
      feedUrl = new URL(MESSAGES_FEED_URI);
    } else {
      feedUrl = new URL(MESSAGES_FEED_URI
          + "?hl=" + USER_LANGUAGE);
    }
    messages = service.getFeed(feedUrl, MessagesFeed.class);
  } catch (IOException e) {
    System.out.println("There was a network error.");
    return;
  } catch (ServiceException e) {
    System.out.println("The service is not available.");
    return;
  }
  // Print the messages feed
  System.out.println(messages.getTitle().getPlainText());
  for (MessageEntry entry : messages.getEntries()) {
    if (entry.getRead()) {
      System.out.print("   \t");
    } else {
      System.out.print("new\t");
    }
    System.out.print(entry.getDate().toUiString() + "\t");
    System.out.println(entry.getSubject());
  }
Where do I get it?
If you want to know more about GData, you may want to start by checking out the GData website. The homepage of the Webmaster Tools GData API contains a section on the messages feed, with details about the protocol. You can also download the sample Message Center client form the GData download site. It will show you how to use all the Message Center GData API features.

Just in time for the holidays, the Webmaster Tools team has updated the "Search queries" and "Links to your site" features.

Search queries with top pages:
Throughout the past year we’ve made some significant changes to the search queries feature in Webmaster Tools. We've received lots of feedback about this tremendously popular feature. One frequent request we heard was that people wanted to be able to see search queries data for their site’s individual pages. Well, we totally agreed that this would be useful and promptly set out to add this functionality to search queries. The fruits of our effort have finally ripened enough on the vine and are ready for you to enjoy. Now when you visit the search queries feature in Webmaster Tools you'll see a new tab titled "Top Pages." The "Top Pages" tab lists impression, click, and position data for the top pages on your site based on their performance in Google's search results.


If you click on one of the individual pages listed you’ll see a list of the queries driving traffic to that page, along with impressions and number of clicks for each query.


Just like in the "Top queries" view, you can click on a specific query to see more detailed data and evaluate how the query is performing across the whole site.


To make filtering in search queries even easier, we've added pie charts to show visually the proportions of search type, location and traffic. Also in the "Top queries" view, you can now specify “containing” or “not containing” when filtering queries.


Links to your site with intermediate links:
Links to your site now shows when a particular URL redirects. If there's a link to your site that links to URL1 which then redirects to URL2, we are now showing the link from URL1 to URL2 as an intermediate link. We also added a "Download all links" option to all the tables in the Links to your site feature.


Now that you know about these updates, please take a few minutes to check them out for your site. We hope it will provide you with a little bit of extra joy this holiday season. Let us know what you think by submitting a comment here or posting in our Webmaster Help Forum. Happy Holidays from the Webmaster Tools team!
