title: When searching through emails in Gmail, how to always exclude hangouts (-in:chats)
body: <p>Every time I want to search through my email, it's slow as can be, because it's also searching through my hangouts history.. I receive hundreds of messages a day, and searching through mail has become quite the chore. Every time I'll have to append:</p>
  
  <pre><code>-in:chats
  </code></pre>
  
  <p>to the search terms. Is there any way for Gmail to stop searching through my hangouts, unless I specify it? <code>in:chats</code>?</p>
