The Essentials of Google Search

...

...
...
The Google webpage will be displayed

6
...
Simply type one or more search terms (the words or
phrase that best describe the information you want to find) into the search box and hit
the 'Enter' key or click on the Google Search button
...
Here are some basic tips to help you maximize the effectiveness of your search:
Choosing search terms
Choosing the right search terms is the key to finding the information you need
...
But it's often advisable to use multiple search terms; if you're planning a Hawaiian vacation,
you'll do better with vacation Hawaii than with either vacation or Hawaii by themselves
...
vacation Haw aii golf
Google Search
You might also ask yourself if your search terms are sufficiently specific
...
But choose your search terms
carefully; Google looks for the search terms you chose, so luxury hotels Maui will probably
deliver better results than really nice places to spend the night in Maui
...
All letters, regardless of how you type them, will be
understood as lower case
...
Automatic "and" queries
By default, Google only returns pages that include all of your search terms
...
Keep in mind that the order in which the terms are typed will
affect the search results
...
For example, to
plan a vacation to Hawaii, simply type vacation hawaii
...
Google will indicate if a common word has been excluded by
displaying details on the results page below the search box
...
(Be sure to include a space before the "+" sign
...
Common words in a phrase search (e
...
, "where
are you") are included in the search
...
Thus, when appropriate, it will search not only for
your search terms, but also for words that are similar to some or all of those terms
...
Any variants of your terms that were searched for will
be highlighted in the snippet of text accompanying each result
...
In this case, simply put
quotation marks around your search terms
...
Negative terms
If your search term has more than one meaning (bass, for example, could refer to fishing or
music) you can focus your search by putting a minus sign ("-") in front of words related to
the meaning you want to avoid
