title: Is Indexing int better than string in realm for react native?
body: <p>Is querying indexed integers faster than indexed strings in realm?</p>
  
  <p>For example,my documents has about 50 fields, and 10 of them are indexed for query. I'd like to know for fields like <code>gender</code>,<code>race</code> that have a limited number of options, would you store them as <code>int</code> instead of <code>string</code>?</p>
