title: StrongLoop Loopback Model find with OR condition on WHERE filter
body: <p>I'm trying to find a person by either their name OR identifier using StrongLoop's Model.find syntax (documentation here: <a href="http://apidocs.strongloop.com/loopback/#modelfindfilter-callback" rel="noreferrer">http://apidocs.strongloop.com/loopback/#modelfindfilter-callback</a>).</p>
  
  <p>But I can't figure out how to specify the OR condition.</p>
  
  <p>I can match both the name AND identifier using this syntax:</p>
  
  <pre><code>person.find({
      where: {
          'name.text': {like: 'Dave'},
          'identifier.value': {like: '3303927'}
      }
  }, callback);
  </code></pre>
  
  <p>But I'd like to be able to match name OR identifier doing something like this:</p>
  
  <pre><code>person.find({
      where: {
          'name.text': {like: 'Dave'} ||
          'identifier.value': {like: '3303927'}
      }
  }, callback);
  </code></pre>
  
  <p>Either this isn't supported or I can't get the syntax correct.  It appears this is supported via the REST API (doc: <a href="http://docs.strongloop.com/display/DOC/Model+REST+API#ModelRESTAPI-Findmatchinginstances" rel="noreferrer">http://docs.strongloop.com/display/DOC/Model+REST+API#ModelRESTAPI-Findmatchinginstances</a>) so I'm hoping it's supported the way I'm trying to accomplish it.</p>
  
  <p>Thanks!</p>
