title: how to handle select boxes in django admin with large amount of records
body: <p>my app has grown so that that drop downs in the django admin have 100,000s of options.  I can't even open my admin anymore because of its load on the database, not too mention I wouldn't be able to find an option in the select box.</p>
  
  <p>Does django have an autocomplete option?</p>
  
  <p>What is the best option for handling big data in django admin?</p>
