I've never fully understood why Google hasn't provided an advanced search option. Even the most primitive library catalogs have one. Sure, there are a few options you can use, but they're extremely basic. Is it because it would reveal key parts of the algorithm? Or is it a stance (i.e., a standard Google search ought to be enough for everybody)?.
