title: Using OR in SQLAlchemy
body: <p>I've looked <a href="http://www.sqlalchemy.org/docs/orm/query.html" rel="noreferrer">through the docs</a> and I cant seem to find out how to do an OR query in SQLAlchemy. I just want to do this query.</p>
  
  <pre><code>SELECT address FROM addressbook WHERE city='boston' AND (lastname='bulger' OR firstname='whitey')
  </code></pre>
  
  <p>Should be something like</p>
  
  <pre><code>addr = session.query(AddressBook).filter(City == "boston").filter(????)
  </code></pre>
