title: Javamail search unread mails with a keyword (multiple searchterms)
body: <p>I know how to search messages with keyword, I also know how to search unread messages. But I don't know how to combine those two things.
  Here is my code:</p>
  
  <pre><code>        Properties props = System.getProperties();
          props.setProperty("mail.store.protocol", "imaps");
          try {
              Session session = Session.getDefaultInstance(props, null);
              //GMail connecting
              Store store = session.getStore("imaps");
              store.connect("imap.gmail.com", user, password);
              Folder inbox = store.getFolder("Inbox");
              inbox.open(Folder.READ_WRITE);
  
              //Enter term to search here
              BodyTerm bodyTerm = new BodyTerm("abcd");
              FlagTerm flagTerm = new FlagTerm(new Flags(Flags.Flag.SEEN), false);
  
              //can only search with one term at one time
              Message[] foundMessages = inbox.search(bodyTerm);
          }
          catch (MessagingException e) {
              e.printStackTrace();
          }
          catch (IOException e) {
              e.printStackTrace();
          }
  </code></pre>
