Hello Everyone, Good Evening
Hopes you are well. I know that you all are familiar with Google Caffeine: a next-generation architecture for Google’s web search. I have just went through one article about it which was written by Vanessa Fox on Searchengineland.com. She cited nice information about Google Caffeine.
She did one experiment for the search query “buffy the vampire slayer” in the current Google as well as Google Caffeine and at the end of it she felt good i.e. better.
After reading this article, I also did one experiment for the query “cheap price selling shirts in ca”. But when I saw the results on new infrastructure, I really disappointed. As I just found one related result to my search query,
[cheap price selling shirts in ca ] which I have listed below:

I then returned to the current infrastructure (i.e. Google.com), but, got the same results. There was just least results(1 or 2) found related to my search query. Check out,
[cheap price selling shirts in ca ]

So, I sent a request to Google development team, that it would be appreciated if you can add this functi0nality to Google Caffeine that categorize that shirts and t-shirts are different product. It may be lots of stuff on the world that will have minor change in the word but product will not be the same.
Are you agree with my suggestion or not? Please, reply in the comment.
