Almost all of us use search engines on a daily basis. When I
need information Google is the first place that I go. Although many of us use
search engines, we don’t know exactly what they are and how they work. So, a
search engine is defined as a program that searches documents for specific
keywords and returns a list of the documents where the keywords were
found. Some of the top search engines
include Google, Yahoo, Bing, and Ask. Below I have provided some information
about these particular search engines.
Google: Personally, I
prefer to use Google when I need information because I think that it provides
the most accurate results of what I am searching for. Google is by far the most popular search
engine and there are over 250 million searches performed in just one day! It is
a crawler base
d search engine which helps to provide relevant information. Its size and scope it covers are the search
engines greatest strengths.
Yahoo!: They are the second most popular search engine,
owning 28% of the market share. Like Google, Yahoo! is a crawler based search engine.
They were actually powered by Google until 2004, but now they use their own
technology. There are around 167 million searches conducted per day using Yahoo!.
Bing Search: This search engine is powered by Microsoft and
is the search engine for the MSN portal site. In 2005, it began using their own
unique database that includes separate databases for images, news, and local
databases. Although the search engine is large, it lacks advanced features,
which puts it at a disadvantage.
Ask: This search
engine has built its own unique data base. Its original debut was in spring of 2001, but
it re-launched in April of 2002. Like Bing Search, the search engine lacks more
advanced features, but it expanded its capabilities by adding a more advanced
search. Sometimes there are paid ad results and its weaknesses include a
smaller database and no direct URL submissions.
