  To add a search manager to your model:
  <code>
      search = SphinxSearch([index=<string>, weight=[<int>,], mode=<string>])
  </code>
  
  To query the engine and retrieve objects:
  <code>
      MyModel.search.query('my string')
  </code>
  
  To use multiple index support, you need to define a "content_type" field in your SQL
  clause. Each index also needs to have the exact same field's. The rules are almost identical
  to that of an SQL UNION query.
  <code>
      SELECT id, name, 1 as content_type FROM model_myapp
      SELECT id, name, 2 as content_type FROM model_myotherapp
      search_results = SphinxSearch()
      search_results.on_index('model_myapp model_myotherapp')
      search_results.query('hello')
