# Update 7 Oct 2010:

# Requirements:
# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby

If you use the findAll(Specification, Pageable) method, a count query is first executed and then the 
data query is executed if the count returns a value greater than the offset.

For what I was doing I did not need pageable, but simply wanted to limit my results.  This is easy 
to do with static named queries and methodNameMagicGoodness queries, but from my research (googling 
for a few hours) I couldn't find a way to do it with dynamic criteria queries using Specifications.

During my search I found two things that helped me to figure out how to just do it myself.

1.) A stackoverflow question.
