title: Price for literal vs int in Amazon CloudSearch
body: <p>I'm designing search domain and here is my problem: I have a few columns, that don't need to be searchable, returnable or faceted. They have only a few possible values and will be used in fq parameter as filters.  The question is: which datatype to go with? Int or literal? </p>
  
  <p>I'll get more maintainable solution with literal, because int would introduce an external dependency to other database/enum in my code. But will using literals increase the price? And how much? Couldn't find the answer in CS documentation.</p>
