Net is a store of information and the deeper you go the better you get. I have been working as a SEM and I frequently need to go through different types of research work online. I know that it is a difficult job to find the exact thing you need on the web unless you are an expert in it. I recently found a software that not only assists you in finding what you need but also gives you the flexibility to go beyond the common search. It is a good
Web Search Tool that can help you in your project.
All the best in your project.
