Web search engines have major impact on people's everyday life. It is of great importance to test the retrieval effectiveness of search engines. Successful searching of information on the internet depends on techniques such as going straight to the information source, guess work and developing strategies for when to use subject directories and search engines. The utility of the web may match the skills of a professional reference librarian because it possesses an ever-changing and extremely heterogeneous document collection of immense proportions. Experiments on major search engines show that the approach to web research mines many high-confidence rules that help understand search engines and detect suspicious search results.
