Your saved Hangouts messages are archived in the "Chats" label. Messages from one Hangout may be saved as multiple threads. You can also label, star and trash your Hangouts messages.
When you search for messages in Gmail, matching Hangouts messages will show up along with matching email conversations. All Hangouts are marked with an icon () so you can easily distinguish them from emails.
