In Ubuntu, Search messages (not global search) no longer works when using; Edit - Find - Search messages and selecting Body from the drop down then searching for an IP, sender, recipient, etc from the headers of messages in the selected folder/s fails to find anything (always did before). The search text is found in the global-messages-db.sqlite file (previously deleted and re-indexed) and Global search does (perhaps not always) find the messages but it's not as simple to see, select and move messages from there.
