Advanced Search Made Easy
You can increase the accuracy of your searches by adding operators that fine-tune your keywords. Most of the options listed on this page can be entered directly into the Google search box or selected from Google's Advanced Search page.
Additionally, Google supports several advanced operators which
are query words that have special meaning to Google. For a complete list,

Google ignores common words and characters such as "where" and "how", as well as certain single digits and single letters, because they tend to slow down your search without improving the results. Google will indicate if a common word has been excluded by displaying details on the results page below the search box.
If a common word is essential to getting the results you
want, you can include it by putting a "+" sign in front of it.
(Be sure to include a space before the "+" sign.)
Another method for doing this is conducting a phrase search,
which simply means putting quotation marks around 2 or more words. Common
words in a phrase search (e.g., "where are you") are included
in the search.
For example, to search for Star Wars, Episode I, use:
Sometimes what you're searching for has more than one meaning; "bass"
can refer to fishing or music. You can exclude a word from your search
by putting a minus sign ("-") immediately in front of the term you want
to avoid. (Be sure to include a space before the minus sign.)
For example, to find web pages about bass that do not contain the word
"music", type:
Search for complete phrases by enclosing them in quotation
marks. Words enclosed in double quotes ("like this") will appear
together in all results exactly as you have entered them. Phrase searches
are especially useful when searching for famous sayings or proper names.
Google supports the logical "OR" operator. To retrieve pages that include
either word A or word B, use an uppercase OR between terms.
For example, to search for a vacation in either London or Paris, just
type:
If you know the website you want to search but aren't sure where the
information is located within that site, you can use Google to search only
that domain. Do this by entering what you're looking for followed by the
word "site" and a colon followed by the domain name.
For example, to find admission information on Stanford University's site, enter:
-
Language: specify which language you would like your results
returned in.
-
Date: restrict your results to the past three, six, or twelve
months.
-
Occurrences: specify where your search terms occur on the
page - anywhere on the page, in the title, or in the URL.
-
Domains: search only a specific website or exclude that site
completely from your search.
-
SafeSearch: Google's SafeSearch screens for sites that contain
this type of information and eliminates them from search results. [
