title: What is the default value of maxResults in contacts API call?
body: <p>I've read the official document of Google Contacts API version 3.0.
  (<a href="https://developers.google.com/contacts/v3/" rel="nofollow noreferrer">https://developers.google.com/contacts/v3/</a>)
  On the part of 'Retrieving all contacts' there is a note saying below:</p>
  
  <blockquote>
    <p>The feed may not contain all of the user's contacts, because there's a default limit on the number of results returned. For more information, see the max-results query parameter in Retrieving contacts using query parameters.</p>
  </blockquote>
  
  <p>I wonder that 'default limit' because I would like to refer to Google's standard for developing.
  Is there anyone who knows the number of default limit?</p>
