  Managing Gigabytes \[KevinBurton\] I can vouch for M.G. as I have a copy and it's a GREAT book. Should be called Managing Terabytes. Its not light reading by any means and you'll probably have to sit down with each chapter for a bit. (\[DavidSpencer\] -- I agree, great thorough book, must have)

• Foundations of Statistical Natural Language Processing, Chris Manning and Hinrich Schütze, 1999

  [Inquery Query help|http://ciir.cs.umass.edu/irdemo/inqinfo/inqueryhelp.html] \[PaulElschot\] \\ This engine has a more elaborated query language than Lucene. However, Lucene supports most of the mechanisms used by the Inquery operators. Recommended: the section on Query Operator Types that makes the distinction between Belief List Operators and Proximity List Operators.
