-Dr. Lalit Kumar
Everyone is comfortable
searching for desired information from search engines. It is very easy to do and
user-friendly. Anyone can learn with the trial and error method. The knowledge of the system is not required for using Google or other search engines. Anyone can
access a large quantum of information with a single click with the help of a search
engine.
Data Mining Tools:
The data mining tools for
advanced search are used to retrieve the desired information quickly. Highly
effective search algorithms are also used on the internet. It depends upon the
search abilities of the user, how effectively he/she finds out the information.
Suppose I want material on Financial Management in Government, preferably in

The search content may
also, be different. These skills of exploring the internet will provide you 10 times more data than the normal search on a search engine.
Privacy Concerns:
There are people, there
are organizations that keep their exposure away from the internet for privacy
concerns. The sensitive information is always not uploaded on the internet.
Details are available and realized from the search engine only if someone
uploads it on any webpage. Without uploading information, it cannot be
retrieved by the users through search engines.
