The search function is broken in Thunderbird 38.4.0 on Xubuntu 15.10. When I use the quick search function on the toolbar (not the quick filter) I can see two emails that match my search, my sent email and a reply. When I click on the reply I'm taken to a screen saying that no emails match my search. When I try to use the Find function from the menu it again claims that there is only one match, the sent email. I have searched, finded, and filtered every single folder in my three inboxes including junk and trash, and I still cannot find the reply I am looking for. This is incredibly frustrating - how can two different searches disagree on whether a message exists? Why can't I just go directly to the email when I click on one of the matches instead of this ridiculous screen with giant writing saying there ARE no matches? I sincerely hope someone can clear this up.
