I was looking for an old email that I had about Re-Animator The Musical. So, in the search bar in the upper right corner of the Thunderbird window, I typed "re-animator". I got 59 hits, and the message that actually contained the string "re-animator" was 27th, when sorted by relevance. All of the other hits were emails which contained the word "animal" or "animals", which to me has nothing to do with "re-animator". I'm surprised that those were considered hits at all, much less that they were considered more relevant than the one message which actually contained the desired string. I actually tried three different searches: reanimator re-animator "re-animator" (i. e. the first two were without quotes and the third was with quotes). All three of these variations had the same problem, though, that messages containing "animal" were ranked before the message containing "re-animator". The desired message contained the word "Re-Animator" (with that capitalization and hyphenation), and also contained "reanimatorthemusical" as part of a URL that was mentioned in the message. So, I would have expected both the search with the hyphen and the search without the hyphen to have been good hits for this message. My question is: How can I tell Thunderbird to search for messages that literally contain the string I ask for, and not get "creative" with the matches, as it seems to be doing for some reason? (I'm using Thunderbird 31.3.0 on Mac OS X 10.9.5.)
