Re:Still doesn't understand the code itself (Score 1)

Sembiance is 100% right that treating code as text will not lead to relevant results. You need to understand the contents. With http://www.krugle.com/ we do parse the code understanding not only the differences between a function call or call definition, but also comments. We take this into consideration when determining ranking - along with the size of the project, amount the codes been used, etc.
