Cache Operator:
Say you want to see all occurrences of the words in your search string Highlighted, in a particular web page. What can you do? Use the ‘cache:’ operator.
Eg: If you wanted all the occurrences of the words ‘web’, ‘net’, ‘browser’ and ‘Google’ highlighted (for easy viewing) in the Netty-gritty blog page; you just need to give the string ‘cache:netty-gritty.blogspot.com web net browser google’ in Google. See for yourself, what it returns!
Now, don’t you think its very useful, especially when you need to find occurrences of strings in a webpage laden with lots of information.?
As you might have guessed the primary functionality of the ‘cache:’ operator is not to highlight search words. So what is the ‘cache:’ operator really meant for?
Google takes a snapshot of each page examined as it crawls the web, and caches these as a back-up. When you use the ‘cache:’ operator, you see the web page as it looked when it was indexed (this is the content Google uses for the search – so if you updated your website recently and want to know if the Google bots have already crawled through your content, you may use the ‘cache:’ operator).
Link Operator:
Know the secret behind Google's huge success as a search engine? It was the hypothesis 'that pages with the most links to them from other highly relevant Web pages must be the most relevant pages associated with the search' - by Larry Page and Sergey Brin, who were Ph.D. students at Stanford University then. Their research project was accordingly named Back-rub, which later went on to be the internet giant Google!
Obviously we could except, some operator which would list all webpages that have links to the specified webpage, right? Well, what we are looking for is the 'link:' operator.
Eg: 'link:www.google.com' will list webpages that have links pointing to the Google homepage. If you had a website/ blog and wanted to see all other pages that link to your page, you know what to do :)
