Over due by several years, Wrox just published a book about Microsoft Enterprise Search, including the different FAST flavours. Bravo!
You can ask how all the users of FAST technology could have managed for so many years without some public source of learning the products. Up until now FAST/MS and their partners have been the sole source of learning FAST Search . Now, we’re part of that eco-system and may have profited on the lack of material available, but that’s another story.
