SEARCH ENGINES |
|
Search
capabilities and results vary widely between different
search engines. While the basics for searching similar, if
you want to create complex queries, the finer nuances can be
very different from one engine to the next. With so many
search engines available, the best approach is to choose
just two or three engines and learn the intricacies of each
of them. |
|
A basic search
using Google... |
To provide an understanding of
the amazing levels and options there are to learning how to
query just one particular search engine, we'll look at
basic, then advanced queries in Google - the top ranked
choice of search engine users.
..
Let's begin by looking at the steps for a basic Google
search...
..
To enter a query into Google, just type in a few descriptive
words and hit the 'enter' key (or click the Google Search
button) for a list of relevant web pages. Since Google only
returns web pages that contain all the words in your query,
refining or narrowing your search only required adding more
words to the search terms you have already entered. Your new
query will return a smaller subset of the pages Google found
for your original query.
.
For best results, it's important to choose your search terms
(or keywords) carefully. By the way, Google will check your
spelling before doing a search, and if you've misspelled a
word, it will offer the correct spelling.
.
The fastest way to find what you need is to be as specific
as possible. If you're looking for the "Acme Budget Moving
Company", enter all those terms rather than just "budget
movers" or "moving companies"
.
If you can't seem to put together the right search query,
try using words that are likely to appear on a site with the
information you want. For example, the words "boxes" and
"packing" would most likely appear on a moving company site.
.
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.
.
Google searches are NOT case sensitive. All letters will be
understood as lower case. For example, searches for "acme
moving", "Acme Moving", and "ACME Moving" will all return
the same results. |
|
Fine tuning
your search... |
You can increase the accuracy of
your searches by adding Operators
to fine-tune your chosen terms.
..
Phrase Searches - Search
for complete phrases by enclosing them in quotation marks.
Words enclosed in double quotes 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. For example, "The early bird gets the worm".
.
"OR" Searches - To retrieve
pages that include either word A or word B, use an uppercase
OR between terms. For example, to search for a home in
either Texas or Montana, just type - home texas OR
montana
.
" + " Searches - As mentioned, Google ignores common
words and characters such as "where" and "how", as well as
certain single digits and single letters. If a common word
is essential, you can include it by putting a "+" sign in
front of it. (Include a space before the "+" sign.) If you
wanted to search for Where's Waldo type where's
+waldo
.
" - " Searches - Sometimes you may want to exclude a
particular word from your search. This can be done by
putting a minus sign ("-") immediately in front of the term
you want to avoid. (Include a space before the minus sign.)
Suppose the thing you're looking for has more than one
meaning - like a new mouse for your computer. You don't want
sites that give you information about the rodent - or tell
you where to get mice for your pet snake. To exclude these,
you would type: mouse -rodent |
|
You're ready
for the Advanced section! |
And now - an advanced Google
search using "Advanced Operators" (There are some pretty
handy tricks here!)...
.
site: If you include site: in your query, Google will
restrict the results to those websites in the given domain.
If you know the website you want to search but aren't sure
where the information is located within that site, you can
search only that domain. Just type what you're looking for
followed by the word "site" and a colon followed by the
domain name. For example, to search for moving tips on the
Realtor.com site, enter: moving tips site:www.realtor.com
(There can be no space between the "site:" and the url.)
.
link: The query link: will list web
pages that have links to the specified web
page. For instance, link:www.realtor.com will
list web pages that have links
pointing to the Realtor.com homepage. (There can be no space
between the "link:" and the url.)
.
related: The query related: will list web pages that
are "similar" to a specified web page. For instance,
related:www.realtor.com will list web pages that are
similar to the Realtor.com homepage. (There can be no space
between the "related:" and the url.)
.
info: The query info: will present some information
that Google has about that web page. For instance,
info:www.realtor.com will show information about the
Realtor.com homepage. (There can be no space between the
"info:" and the url.)
.
stocks: If you begin a query with the stocks:
operator, Google will treat the rest of the query terms as
stock ticker symbols, and will link to a page showing stock
information for those symbols. For example, stock: elnk
yhoo will give you information about Earthlink and Yahoo
stocks. (You must type the ticker symbols, not the company
name and there is one space after "stock:")
.
cache: The query cache: will show the version of the
web page that Google has in its cache. Cache is the snapshot
that Google took of the page as it crawled the web and the
page may have changed since that time. For instance,
cache:www.realtor.com will show Google's cache of the
Realtor.com homepage. (There can be no space between the
"cache:" and the url.) This is pretty handy if a site or
page is no longer available online but you still need to
access the information. |

Beyond the
Google web search... |
As you can see, there's quite a
bit more to using a search engine than meets the eye. Now
that you've learned the intricacies of searching for a web
site on Google, before mastering your next search engine,
you might want to take a look at some of the additional
services and tools offered at Google. There are many more
things you can search for besides web sites. For instance...
