title: Elastic Search Analyzers and Facets
body: <p>I am evaluating Elastic Search for a client. I have begun playing with the API and succesfully created an index and added documents to the search. The main reason for using Elastic Search is that it provides facets functionality. </p>
  
  <p>I am having trouble understanding Analyzers, Tokenizers and Filters and how do they fit in with facets. I want to be able to use keywords, dates, search terms, etc as my facets. </p>
  
  <p>How would I go about incorporating Analyzers into my search and how can I use it with facets?</p>
