The Internet is one of the most significant technological developments of the 20th century and it is the world's most efficient means of communication (Burton, 2011). Since the inception of the Internet, more information is available to people. The Internet is seen as the network of inter connected computers. In the Internet, files from website(s) are contained, every website is also identified using an address for easy location of the website. For instance Google (www.google.com), is a search engine. The search engines crawl through the websites for information, and then through special algorithm provides organized results for search queries.
According to Ross (2012), search engine is a computer software, designed to help users locate information available on the web by selecting categories from a keywords or phrase. Search engines are good for finding specific information. It assists one to retrieve a lot of relevant sites, because there are so much information on the web.
Several authors have given number of search engines in the Internet. Karl (2012) stated that there are 100 search engines, to Lauren (2012), there are 100 search engines, to Reith (2011), there are 40 search engines while to Kim (2013), there are 25 search engines. Hence there is no agreement on the number of search engines.
Paul (2014) noted that there are 7 major search engines. These are: Google, Google scholar, Bing, Yahoo, Blekko, Ask and web crawler. Each of the major search engines, on which the researcher will focus provide some characteristics that enable users get peculiar benefits. In using the major search engines according to Paul (2014), Google is very useful for online shopping, location and posting of articles on different subjects. Google scholar helps an individual to search through, thousand of guaranteed scholarly articles and research report. Bing contains more of concepts. Yahoo helps to get fast access to translation on institution. Blekko contains information on government sites, as well as different postal codes. Ask contains a lot of magazines, and also provide free social media sites. Web crawler contains more of scientific journals, articles and also different scientists (Paul, 2014).
These major search engines According to Zhou (2005), contain some features like e-mail which will enable users to get information. They also contain local and international news, as well as health information, news and jobs. The features of search engines are also used for other purposes like flashy advertisement and entertainment.
Gile (2001) noted that search engines are used by huge range of people, for a wide variety of purposes, and they have different perception of search engine nature. Moses (2012) stated that undergraduate students are not aware of the other major search engines apart from Yahoo and Google as well as the benefits contained in them. This will reduce the use of the other major search engines (Moses, 2012).
In using a search engine, an individual is not searching the entire web, but a portion of the publicly available pages on the web. Search engines are very important when it comes to communication, and has even broken the barriers of distance. According to Brabozon (2001), an academic institution can communicate with its students with their website that are picked by search engines.
Jagboro (2003) opined that search engines serve as source of information to students, researchers and lecturers in higher institutions of learning. This will be an avenue, through which researchers can access past and current research publications and make adequate use of them. Students can also access information on various courses offered to them in the institution. This will make them have different information materials for their assignments and research work. Search engines also provide easy access to some government documents, and legislative materials like journals, magazines and newspapers. Search engines provide e-print in details and other types of digital works by authors in an academic department, school or institutions which comprise of electronic theses and dissertations and presentations by authors of different institutions. This has enhanced the potential for wide spread online search and retrieval of electronic content easily.
The aim of search engines according to Butters (2009), is to search and navigate, meaning that a successful search engine should support its users in an efficient search for contents, and bring detailed information resources with ease to various undergraduate students. Mark (2012) noted that the search engines available are very many but due to lack of...
