Charles Rezac ...
   Can anyone suggest a good book or selection of books providing a
   concise introduction to full text databases -- preferably one with
   discussion, algorithms and code for high speed full text indexing.

I've "gotten value" from "Automatic Text Processing" by Gerard Salton
published by Addison-Wesley.  I paid $41.75, but then, I didn't buy it
from Crown.  The beginning of the book is pretty elementary and the end
of the book is pretty theoretical.  The stuff in the middle describes
text indexing completely enough for one to do one's own
implementation.  The book does not include code, but does includes
extensive references to research papers on its various subjects.
