I'm literally in the library right now, working on my last homework for a Search Engines course taught by Distinguished Professor Bruce Croft. We're using his new book, Search Engines: Information Retrieval in Practice. You can find the slides that accompany the book here:

The book expands on the slides, as well as includes homework problems, some requiring the use or modifications of the open-source Galago Search Toolkit.
