Case Sensitive Search in Yahoo!
Case sensitive searches help when searching a person’s name and certain words such as the month of March, rather than a marching band, or a person from Poland is Polish, not silver polish.
CaseSensitiveSearch.com appeared in April 2013 and provides a case sensitive web search engine based upon the Yahoo! search engine database. However, this search is based on a paid service called BOSS that allows developers to create custom Yahoo! search engines for a fee. In this case, we do not know what pricing plan the developer is on, therefore, we do not know what portion of the Yahoo! index the thing searches.
