In this thesis we implemented a software system for search engine comparison and value addition. In the comparison part, the system can be used to compare the search result quality of different search engines. The comparison can be between two local search engines or between two web search engines. Two popular open-source search engines, elasticsearch and solr have been choosen to be compared in our study. The value addition part can be used to provide search result management on popular web search services such as google web/news/video search and youtube search. The operations provided include 'ranking-adjustment', 'like', 'deletion', etc. Through such value addition, the user can manage the search result to be more valuable knowledge for their own use.
