Ask HN: What resources are there for Search/Information retrieval?

[johnbroccoli]

Other than going through the source code for Lucene/Solr, what books, articles or any other resources would you recommend that go over the theory/math/design of a Search system?

[johncoogan]

Introduction to Information Retrieval by Manning, Raghavan, & Schutze is my favorite. Available here: http://nlp.stanford.edu/IR-book/

Awesome! This looks really useful.
