Web search engines like Google offer serendipitous discoveries, surprising users with content that they never expected to exist. Instead of such discoveries being merely lucky accidents, search engines should enable users to find such unusual information, also called outliers, more often and regularly. Determination of outliers plays a crucial role in search functions of web search engines. Searching for outliers is crucial for a professional information researcher, as they make researched information more effective and valuable than regular search engines output. Outlier search is often a traditional style of search. While searching for unusual information, the user must remember that the information is not unusual to the provider. Regular search engine outputs are a just carefully indexed sequence of information which is already known to the user. Outliers can help clients by providing an edge in attracting funding agencies, winning grants, or getting their work published in renowned publications. The search for outliers should begin from high-quality sources. The terminology used for the search must be altered and refined by cross-checking with other high-quality abstracting and indexing services. Such refinements usually help in giving the searcher a feeling that he triumphed in the face of adversity and secured a winning run for the customer. In research situations, outliers provide clients with information vital for business.
