title: How to search imap inbox with mailkit based on multiple condition?
body: <p>I want to search imap inbox  with mailkit  based on multiple condition like NotSeen &amp; NotDeleted. I know the queries are receptively,if we do individual search query.</p>
  
  <pre><code>var uids = client.Inbox.Search(SearchQuery.NotSeen); 
  var uids = client.Inbox.Search(SearchQuery.NotDeleted );   
  </code></pre>
  
  <p>but i need to put those two queries together &amp; get all Uids based  on the conditions.
   Any help would be appreciated.</p>
