an internet search engine
when used in a basic way return too many hits, and it can be very
time consuming looking through all those web sites. So how can we
get more accurate search results?
We need to include
operators in our search strings - operators being "",
+, -, ~, ..
like Google ignore common words like "how", "are",
as well as most single digits and single letters. If you put a "+"
sign in front of a common word it will be included in the search.
You can also do a phrase search by putting the phrase in quotations.
Lets say I was
doing a search for the movie Back to the Future 1 this
is what I would type.
back to the
future +1 or "back to the future 1" this
would narrow my search and not show results with the movies part
2 or part 3.
sign in front of a word will exclude that word. A good time to use
this is when searching for things like Bass. Now its fishing and
not music I'm after so this is what I would type.
This would exclude anything to do with music.
You may want
to search for a particular keyword, but also for synonyms. We use
the "~" tilde symbol in front of the word. Example of
this would be if I wanted to search for food facts and nutrition
and cooking information I would type.
You can also
use the logical "OR" operator to find sites that include
either word A OR B. This is an example.
london OR paris
Next we look
at searching whithin a particular site. You can do this in Google
by entering the word "site:" and a colon followed by the
web site. Say I wanted to search for "button" on www.picketpost.com
I would type in.
The last one
is an important one when searching dates. By using 2 periods ".."
between numbers this is looked at like a range. Here is an example.
canada maps another example is money metal detector $200..500
will help you find what your looking for faster allowing you to
spend more time digging.
