title: How do I set more than one index for a table in a doctrine 2 entity file (using annotations)?
body: <p>I have two columns representing a start date and an end date.
  If I wanted to create a joint index for them, I would do:</p>
  
  <pre><code>* @Table(name="concerts", indexes={@Index(name="concert_dates", columns={"date_start","date_end"})})
  </code></pre>
  
  <p>But how would I do an index for each of them ?
  Is the following way correct?</p>
  
  <pre><code>* @Table(name="concerts", indexes={@Index(name="concert_date_start", columns={"date_start"}), @Index(name="concert_date_end", columns={"date_end"})})
  </code></pre>
