title: How to give weight to result which contains repeated words in hibernate search
body: <p>I am using hibernate search with combination of different queries like keyword, phrase, fuzzy etc. It is working as expected. The only thing i cannot recognize is how to give higher weight to a result which contains repeated words.
  For exp.
  I have 3 index</p>
  
  <ol>
  <li>"word"</li>
  <li>"word word"</li>
  <li>"word word word"</li>
  </ol>
  
  <p>Now if I provide search keyword "word" it should return index 3 with higher weight then index 2 and then index 1 with lower weight.
  I googled a lot but couldn't find anything. Can we do this using hibernate search?</p>
