There are different kinds of search tools available to us or
the internet, including directories such as Yahoo!
These are arranged in
a particular hierarchical form of categories. Navigating through directories
requires “drilling down” to a website
of the internet. Search engines use web crawlers or spider bots to process a
search. Each search engine has a unique algorithm that is key to the results
presented. The information collected varies from site to site but may include
the page title and URL. Searches like Google use what is called a “Natural Language Search” and there is
no question as to why this is so popular. It more closely resembles the
language we use. It uses Boolean techniques to allow for an infinite
combination of variables to define the search criteria. The “and” operation can narrow the returns
with only the inclusion of “A and B”
results. While the “or” operation
would allow a wider range for “A and B”
and the “not” will limit the results
to just “A” and not “B”.
With a
basic knowledge of set theory, one can comprehend the scope of these variables
in a search operation. The full explanation can be found at the link below.
The
competition between the search engine giants is fierce! It’s not surprising,
considering the value of the player’s stock and reputation. Google stock is
hovering near $1000 and the story about Bing copying Google was all over the
news a few years ago.
Bing is running behind the Google giant and that’s not so
easy for a dominant force such as the Microsoft corporation, the
wheels behind the Bing search engine.
