Google is not particularly strong at letting you determine the freshness of search results. The vagueness surrounding page freshness is due to several reasons:

  • Google uses more than spiders to crawl the Web, and more than one type of spider.These crawlers operate at different speeds and different depths. It’s possible for a newly created Web page to go undetected by one crawl and then turn up in the index two weeks later after a deeper crawl.

  • Google uses more than one server (Internet computer) to deliver search results. The servers are not perfectly synchronized. At any moment, one server might give slightly different search results than another server. This fact, plus the multiple spiders, results in what observers call the Google dance.

  • The freshness of a page is determined by the time it was created, or the time it was added to Google’s index, or both.

Google does enable a certain degree of freshness filtering on the Advanced Search page in Web search.On the Advanced Search page, you can ask for Web pages updated within the past three months, six months, or year. These large time frames are safe for Google, because the three variables just listed cause confusion only within time periods shorter than three months.

An alternate Google engine called GooFresh invites you to fine-tune the freshness setting by drastically narrowing the time frame. GooFresh is located here:

GooFresh accomplishes the time-narrowing trick by using the daterange operator. I don’t discuss this operator much in this article because daterange doesn’t understand dates formatted in a typical fashion — month, day, and year. Google understands only the Julian date system, which involves long and cryptic strings of numbers. Online Julian date converters are available for use with the daterange operator. If you do so, you are still subject to the Google dance depending on when a page is added to the index and when it hits all the servers.

Assuming that your freshness needs aren’t too precise or imperative, GooFresh is a fine alternative. The search results look completely normal and are drastically narrowed compared to an undated search. A recent search for the keyword internet, which normally returns hundreds of thousands of results, yielded only three when GooFresh looked for pages added on the current day.

Google is far more than a search siteit has grown to be a sizable collection of services and tools, and the collection is getting larger all the time.

Arguably, the most useful of Google’s specialty search areas is that devoted to the U.S. government. Actually, this distinct search engine is both larger and smaller than the name implies. This engine is global in reach. At the same time, it reaches below federal government sites to the state and municipal level. You might think that this entire search engine merely replaces the site:.gov operator:keyword combination. Not so. In fact, site:.gov remains quite useful in the UncleSam search because the results pages dish up a hear...

4. Google Search Operators
Google allows you to search using search operators, special words and symbols that make it easy to get search results that match as closely as possible the information for which you're looking. You combine search operators with search terms to form a query, like this: zeppelin "Led Zeppelin" That search would bring back pages that had the word zeppelin on them, but did not have the term Led Zeppelin on them. Here are the common operators you can use with Google: ...

7. Google`s Approach to Online Shopping
The main difference between Google’s shopping services and those in other major portals is that Google doesn’t get its hands on the money. You don’t buy anything through Google. Both Froogle and Google Catalogs function purely as directories to products, sending you elsewhere to get your hands on the goods. Google has no revenue-sharing association with e-commerce retailers (in Froogle) or mail-order companies (in Google Catalogs). The search results you get in both services are pure; preferred placement in the search resul...
