Developers and other search geeks out there might find this draft document that lists and discusses a number of search interface protocols and specifications worthy of a read/bookmark. The paper comes from the CORDRA project at Carnegie Mellon University. Thanks to Puzzlepieces for the tip. Btw, Michael Fagan (publisher of Puzzlepieces) also notes several other protocols/specifications that aren’t listed in the paper.
