Use Google Search Operators
Search operators are characters that narrow down your search query to get more specific results. You can tell Google, for example, to omit certain words from the results or to find pages that have all of the words you specify in the page.
Google has a few search tools that, when used together, can unlock numerous downloads:
inurl, intitle, and filetype.
For example, to find free Android APKs, you’d search for
-inurl:htm -inurl:html intitle:”index of” apk
to see site indexes of stored APK files.

Get “Wildcard” Suggestions Through Autocomplete
You can get wildcard suggestions by typing in a full phrase in Google and then deleting the word you want to replace.
For example, you can search for how to jailbreak an iPhone and remove one word to see all the suggestions for how to ____ an iPhone.
Get alternatives to popular Softwares, Sites, and Products.
Just type in something vs and see what Google’s autocomplete adds. It’ll most likely list the most popular competitors to the something so you know what else to check out.
You can also search for better than something to see alternatives, too.
Bypass firewalls using Google Proxy
Google services are designed to help you in your everyday life, but they can be exploited to do many more things than they were actually built for.
For example, you can unblock websites and bypass firewall restrictions using the never developed Google Proxy. Actually, Google don’t provide any such service but a trick can be used to make Google Translate and Google Mobilizer do this job.
opens up Example.com even if it’s blocked.
allows you to view Example.net even if it comes under your firewall’s block rule.
Search something on certain sites
If you really like a web site but its search tool isn’t very good, Google almost always does a better job, and you can use it to search that site with a simple operator.
For example, if you want to find an old Times Of India article, just type site:timesofindia.indiatimes.com before your search terms
(e.g. site:timesofindia.indiatimes.com xyznews).
The same goes for your favorite forums, blogs, and even web services.
