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, perform the following search and you’ll only get pages that contain the word “Hello” followed by the word “World.”
Excluding a Word
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 site: operator allows you to perform a search in a specific site. Let’s say you’re looking for information on Tips on Phonegadgetz.blogspot.com . You could use the following search
site:Phonegadgetz.blogspot.com TipsYou can also use the site: operator to specify a domain. For example, if you’re looking for high-quality references, you could use site:.edu to only pull up results from .edu domains.
The tilde (~) operator is the opposite of enclosing a single word in quotes — it searches for related words, not just the word you type. For example, if you ran the following search, you’d find search results with words similar to “geek”:
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”
A little-known search operator allows you to specify a specific time range. For example, use the following search to find results about Ubuntu from between 2008 and 2010:
The filetype: operator lets you search for files of a specific file type. For example, you could search for only PDF files.
filetype:pdf Computer history
One Word or the Other
The “OR” operator lets you find words that contain one term or another. For example, using the following search will pull up results that contain either the word “Ubuntu” or the word “Linux.” The word “OR” must be in uppercase.
ubuntu OR linux
You don’t have to Google a word and look for a dictionary link if you want to see its definition. Use the following search trick and you’ll see an inline definition:
Use Google instead of pulling one out or launching a calculator app. Use the +, -, * and / symbols to specify arithmetic operations. You can also use brackets for more complicated expressions. Here’s an example:
(4 + 2) * (6 / 3)
The calculator can also convert between units. Just type “X [units] in [units]”. Here’s an example:
5 nautical miles in kilometers
