Google search, besides searching for content in websites, incorporates various functions that activate either based on a prefix or on the form of the search request. I knew that these functions were present and used some of them at one time or another. The functions I used was address lookup by entering the phone number, calculator, maps, site information, word definition and currency and measurement conversions. Now all of these functions are not really related to any outside company and are not something unexpected.
Recently, I tried a new kind of search with surprising results. Having in mind the different functions that at incorporated into Google search, I decided to type in a UPS tracking number. I was quiet surprised when Google redirected me to the UPS tracking detail page. Usually, when I want to lookup the progress of my package, I have to go to UPS website, enter tracking number, click agreement box and click submit. I very much don't enjoy all that typing and clicking. Now, with the power of firefox and Google, I can just type in the UPS number into the search box and press enter. I looked up on Google's search help what else can google do. Google can give you weather if you search for "weather zip". You can enter FedEx and USPS tracking numbers for tracking information. You can look up UPC codes, vehicle ids and patents. Besides these there are also unlisted search patterns.
Some may say that these services are evil in some way or another, that Google is becoming a monopoly, I, for one, welcome our new Google overlords. The more services are integrated into Google search, the better.
P.S. as I was writing this, I tried to search for "show times transformers". Above the search results, Google presented me with a link to the Transformers trailer, movie length, average rating and link to collection of review from different sources and a form input to enter my zip code. After I entered my zip code and clicked submit, I was presented with a page within Google that showed 13 closest movie theaters and show times for the movie. I love Google!!!
