Getting desired results from google

Google is the most widely used search engine. But it has lots more up its sleeves than just showing simple search results. Using some of the following tricks you can get a lot of  detailed results from Google search which are generally unknown.

Exact Words and Phrases:

One of the most basic and widely known search tricks is using quotation marks to search for an exact phrase. For example, if you seaerch "Hello World" you’ll only get pages that contain the word “Hello” followed by the word “World.”

Site Search:

You can search the name of the websites with a definite wrod int it by typping intitle:your word.
For example, "intitle:hacking" (without quotes) will give out the names of the websites containing the word hacking.

Excluding Words:

The minus sign allows you to specify words that shouldn’t appear in your results. For example, if you’re looking for pages about Linux distributions that don’t mention Ubuntu, use the following search:

Linux distributions -Ubuntu

The Wildcard

The asterisk (*) is a wildcard that can match any word. For example, if you wanted to see what companies Google has purchased and how much they paid, you could use this search:
Google purchased * for * dollars

Special Info:

Certain types of searches will show you special information directly below the search box.
   
 Weather: [ weather edinburgh ] 
 Calculations: [ 45 x .88 ]   

One Word or the Other
