title: AND (&) disjunction in Parse IOS SDK
body: <p>I've been going over Parse's API for custom/relational queries, and was not able to find an example of creating a query that simulates that of an AND disjunction. For example, I would like to find an object whose "first" and "last" columns match values "John" and "Doe" respectively. The orQuery that exists in the PARSE API is a method simulates the OR conjunction (at least to my knowledge), so it's not what I need.</p>
  
  <p>Any ideas on how to achieve this functionality (example would be great)?</p>
  
  <p>Thanks</p>
